Classification

This document distinguishes between engine-native bugs (reproducible in vanilla) and RHS-Status-Quo mod-specific bugs. A significant number of issues are server-side memory/component leaks that cannot be resolved by RestartMission; a complete server process restart is required.

I. Critical Server-Side Low-Level Bugs (Engine-Native, Reproducible in Vanilla Without Mods)

1. VehicleAudioComponent — Vehicle Audio Pool Leak (Highest Priority)

1. Timing race deadlock: Spawning vehicles immediately upon OnMissionStart results in the first vehicle having no engine sound; all subsequent tanks, trucks, and armored vehicles in that session lose engine audio. Tire, collision, and weapon sound effects remain normal. The reproduction rate is considerably higher on Linux dedicated servers than on Windows.

2. Runtime leak: Audio functions normally at session start; after 1–2 hours of server uptime, following engine stall during coasting, collision/rollover, or in-vehicle crew swap, the vehicle audio component is destroyed. Progressively, large numbers of vehicles become silent — affecting all players, not a single-client issue.

3. The issue is also reproducible in the Workbench editor preview; Shift+R scene restart does not reset the audio pool — the Workbench process must be fully terminated.

Workaround: Introduce a 0.8–1.2 second delay on OnMissionStart before spawning vehicles; avoid pre-placing large numbers of vehicles in the mission; for extended campaigns, perform a full server process restart every 90–120 minutes.

2. MagazineComponent / WeaponComponent — Weapon Component Resource Leak

1. After prolonged server runtime (approximately 2 hours), with repeated creation and destruction of weapon/magazine entities, component instances cannot be reclaimed, resulting in resource pool exhaustion.

2. Symptoms: The magazine displays remaining ammunition, but pulling the trigger produces no response — no firing animation. Reloading or dropping and re-equipping the weapon temporarily restores functionality, but the issue rapidly recurs. Vanilla BI weapons exhibit low probability; RHS mod weapons severely amplify the leak.

Workaround: Implement scheduled script-based garbage collection of abandoned weapons, magazines, and corpse wrecks on the ground; reuse arsenal entities rather than repeatedly destroying and spawning weapons; schedule full server restarts.

3. UI-GPU Texture Memory Leak (Client-Side, Low-LOD VRAM Bug)

Key new finding: Client VRAM memory leak forces objects to switch to the lowest LOD.

Symptoms:

1. After 30–90 minutes of gameplay, with repeated opening of the map, inventory, and radial menu, VRAM usage continuously increases without release. This is not a physical VRAM capacity limitation — engine resource reclamation is non-functional. The issue is reproducible on 12GB and 16GB graphics cards alike.

2. Manifestation: Characters, vehicles, and buildings abruptly render as polygonal low-poly models with blurred or missing textures; distant object LOD behaves abnormally, and near objects are also forcibly downgraded. FPS drops sharply, screen flickering occurs; in severe cases, UI icons disappear and the client crashes.

3. Restarting the mission alone is ineffective — the game client must be fully exited and relaunched to recover. Server-side RestartMission cannot resolve client-side VRAM leaks.

4. Mods (RHS and other heavy vehicle/weapon mods) accelerate the onset of VRAM leaks exponentially.

Log signature: Frequent RESOURCES (E): ==== Resource leaks ==== UI texture resource errors.

Client-side mitigation:

1. Reduce frequent opening and closing of the large map and inventory panel.

2. Avoid leaving the game running for extended periods; it is recommended to exit and relaunch the client every 60–90 minutes.

3. Clear the game shader cache; disable Windows spatial audio.

4. Graphics settings: moderately reduce texture quality; do not max out the VRAM budget.

5. Server-side: reduce bulk spawning of vehicles and AI simultaneously to lower client-side resource streaming pressure.

4. Radio Relay Logic Bug

Squad members in close physical proximity but outside relay range experience complete failure of short-range radios, rendering voice communication impossible.

5. Network Synchronization Issues

1. Remote entity streaming anomalies: distant AI and vehicles exhibit partially desynced animations and audio.

2. Certain proxy objects generate null-reference warnings, flooding logs with errors and occasionally causing server crashes.

II. Vehicle-Native Bugs (Vanilla)

1. Engine restart following coasting stall very readily triggers the audio component destruction bug.

2. Dashboard lighting on certain vehicles can penetrate the vehicle hull.

3. Some wheeled vehicles exhibit idle roll on inclines; handbrake assist was improved in version 1.8 but has not been fully resolved.

4. Turret rotation audio disappears concurrently with the VehicleAudioComponent leak.

III. Weapons & Feed System (Engine-Native)

1. Magazine sticking bug: The magazine becomes lodged inside the weapon and cannot be removed; ammunition is displayed but firing is impossible — only firing the magazine to empty restores normal operation.

2. After attachment switching on certain weapons, aim-down-sights (ADS) occasionally fails.

IV. AI, Mission, and Script Bugs

1. Changes to AI sleep/wake spawning logic cause abnormal AI generation in some custom missions.

2. Bulk simultaneous entity spawning readily triggers various component initialization timeouts.

3. Certain Action components generate null references upon deletion, causing occasional crashes.

V. RHS Status-Quo 0.14 Mod-Specific Bugs (1.8 Environment)

The mod amplifies engine low-level leaks; these are not engine-native issues.

1. M27 + M995 feed jam: M995 projectile parameters are incompatible with the M27 feed stroke; jamming occurs after several rounds, and pressing R to clear temporarily restores operation. M855/M855A1 function normally; the M4 Block-II with M995 is largely unaffected.

Workaround: Disable M995 magazines for the M27; remove M995 from the M27 allowed ammunition list in the editor.

2. RHS radial menu HUD freeze: Dying or entering a vehicle while the radial menu is open causes the menu to remain permanently on screen, persisting through respawn.

3. Certain weapon lights exhibit abnormal IR mode cycling (partially resolved).

4. Mod weapons exacerbate server-side MagazineComponent leaks, accelerating late-game weapon firing failures; the large volume of RHS model textures worsens client-side VRAM leaks, causing low-poly/blurry rendering to occur earlier.

VI. Client-Side Local Bugs (Singleplayer / Multiplayer)

1. Bluetooth headsets: Certain 3D audio channels are lost, and some vehicle and ambient sounds disappear; wired or 2.4GHz headsets are recommended; disable Windows spatial audio and Nahimic/Dolby audio enhancements.

2. Steam Instant Replay occasionally produces recordings with missing audio.

3. 2D high-magnification optics cause significant FPS degradation on low graphics settings.

Server Administration Summary

1. RestartMission does not reset server low-level component pools; leak bugs will not be resolved — the server process must be fully terminated and restarted.

2. Do not spawn vehicles directly on OnMissionStart; introduce a 1-second delay.

3. Implement scheduled script-based cleanup of corpses, dropped weapons, and magazine wrecks to reduce entity accumulation.

4. Extended campaigns: perform a full server process restart every 90–120 minutes; concurrently advise players to restart their game client every 60–90 minutes to mitigate the VRAM low-LOD bug.

5. RHS servers: it is recommended to configure the M27 to remove M995 ammunition access, reducing feed errors and delaying the onset of component leaks.

6. Linux dedicated servers have a higher probability of audio initialization bugs; Windows server-side is preferred where feasible.

Current Status: All issues listed above correspond to existing tickets in the BI feedback tracker. No official fix patch is available for the 1.8 release at this time — only script-based and operational workarounds are possible.
