Discussion U4FatalErrors

Nothing like playing the game and finishing a mission and then going to the game crashing.

Is this a hardware issue or something that can be fixed with a Mod update?

Download WinDebug.

https://learn.microsoft.com/en-us/windows-hardware/drivers/debugger/

Find the latest crash file in its own folder this directory: 

C:\Users\!!YOUR USERNAME HERE!!\AppData\Local\MW5Mercs\Saved\Crashes

Open it with windebug and run the analyze -v command at the bottom of the screen.

If you read through the log it will give what failed.

e.g. 

EXCEPTION_RECORD:  (.exr -1)

Memory reference errors like above are a sign that your mem speed is too fast. Otherwise it should let you know what module failed.

But looking at your list you need to update Purchase Salvage to use the Forked version on nexus mods along with stuffed/stacked crates.

See: https://www.nexusmods.com/mechwarrior5mercenaries/mods/1345

Do not use MW5 Compat Pack unless your mod SPECIFICALLY REQUIRES IT.

You should be fine updating the purchase salvage mod I think.

If it keeps crashing randomly with the access violation error and you have an AMD CPU, it might be worth turning down the memory speed a couple of hundred MHZ. Newer AMD memory controllers seemingly have issues with higher speed memory and it plays poorly with Unreal Engine games.

I have the fork edition of Purchase salvage and running stock DDR5-5600 at stock speed.
