Description

Hovering the mouse on/off a service icon on the Conflict game mode's campaign map repeatedly throws a non-fatal NULL pointer to instance VM exception for the m_wServiceHint variable in SCR_CampaignMapUIBase::ShowServiceHint, called from SCR_CampaignMapUIService::ShowHint (OnMouseEnter/OnMouseLeave). These errors repeat continuously without immediately crashing the game, but after several minutes of repeated triggers, the client crashes with an unrelated-looking Unhandled exception: Access violation at a near-null address (0x49). This looks like a case of the recoverable VM exceptions silently corrupting engine memory until a later, unrelated dereference finally crashes the process — similar in pattern to T199581 and T199893.

Steps to reproduce:

  1. Load into a Conflict game mode session.

  2. Open the campaign map.

  3. Hover the mouse cursor on and off a service icon (e.g. supply point/HQ) repeatedly.

  4. Continue playing normally — the errors will repeat silently in the background.

  5. After several minutes, the client crashes with an unhandled access violation.

Expected result: Hovering over service icons should show the intended tooltip without throwing a null pointer exception; no crash should occur.

Actual result: Repeated null pointer exceptions on hover, followed by a deferred, unrelated-looking access violation crash.

Relevant log excerpt:

I used claude for this and gave it all the necessary information for this report, I dont know why it wont work, the random crashing and the lack of connection, as it just keeps showing no connection to server when im in the menu.

My user is PoweringCag on discord if thats any help.
