Windows 11 24H2 triggers ancient bug causing Skimmer plane to get propelled to broken coordinates on spawn

[holmes000]

Describe the bug

Very detailed explanation here: https://cookieplmonster.github.io/2025/04/23/gta-san-andreas-win11-24h2-bug/

Short: Missing vehicles.ide values should have always caused issues, but only in 24H2 fgets/LeaveCriticalSection uses enough stack to scramble the stale values in CFileLoader::LoadVehicleObject.

Fix in SilentPatchSA by CookiePLMonster: CookiePLMonster/SilentPatch@881aded

Steps to reproduce

1. Install Windows 24H2
2. Launch MTA:SA
3. Spawn Skimmer through freeroam (spawns nearby, teleports to invalid coords, you don't get to see it) or through admin panel (spawns and warps you inside, you get launched to invalid coords)

MTA is likely hooking the IDE loading in a way that remedies this bug already. The main point is just those few potentially-uninitialized values.

I created this issue after reproducing it in latest debug build of MTA from master branch, Windows build 26100.3909, KB5055627

I've updated everything on my PC and i can't figure out what and why causes. Everything looks normal. I have latest Windows & latest nVidia drivers.

As this is caused by uninitialized variables, it's likely that this either only manifests in Debug builds or only in Shipping builds. It's easiest to just check the IDE loading code, the bug is understood well enough that you don't particularly need to reproduce it to fix it.
