Dedicated Server Update Breaks Persistence on Modded Game Master Scenarios
Description:
Following the latest Dedicated Server update, persistence is no longer working on modded Game Master scenarios.
Issue:
Persistence worked correctly before the dedicated server updated.
Approximately one hour after switching our server to a modded Yellowstone Game Master scenario, the dedicated server automatically updated.
Since that update, persistence no longer functions.
Using Bacon’s Server Admin Tools to force a save returns:
“Persistence System not found in the game world.”
The issue occurs on all modded Game Master scenarios/maps, regardless of whether additional mods are enabled.
The issue still occurs when loading only the modded scenario with no additional mods active.
Vanilla Game Master scenarios appear to save and load persistence correctly.
Expected behaviour:
Persistence should function on modded Game Master scenarios as it did prior to the dedicated server update.
Actual behaviour:
Modded Game Master scenarios cannot create or load persistence saves, making persistent campaigns impossible.
Environment:
Platform: Dedicated Server
Game Version: Latest update
Scenario: Modded Game Master scenarios (including Yellowstone)
Additional Mods: Issue occurs with or without additional mods enabled
We have been able to reproduce this consistently across multiple modded Game Master scenarios. The issue does not appear to be related to a specific map or mod, as all modded scenarios are affected while vanilla scenarios continue to function correctly.
This suggests the issue is related to the latest Dedicated Server update affecting persistence support for modded Game Master scenarios.
