Hey Nosseric, this is mod-related, but I’m not entirely confident which one. Do you use the **Train Timer** mod?

Hi Julia,

I thought that it was mod-related since the mod pack uses quite a few mods. I can paste my mod\_load\_oder txt, maybe you know which of the mods that I am running is the culprit. If not, I will have to disable them based on the category and single the one out which is responsible for the crashes. I do not use the train timer mod.

I can’t be 100%, but **FullAuto** possibly?

The mod might be it, I disabled it and I have not had any crashes with this error message. However, my game crashed once with a different message, but I was not able to recreate it since. Will post anything, if it comes up again. Thank you for your help.

This is the error message from my latest crash:

Got it - if the `Access violation` crashes start to become more regular, look at lowering your ‘Worker Thread’ count within the launcher’s ‘Settings’ menu to improve stability. 🙂

Did this crash happen right after a psyker left the game?

the crash references this psyker vfx, and when it gets unloaded the game crashes

the LessAnnoyingArbites mod is potentially a cause of the ‘trying to unload resource crash’, you could try disabling it and seeing if it happens again. There are a few other mods that are potentially also causing this issue such as vfx\_limiter and fxlimiter

I do not rember whether a psyker left the game but I played psyker and at the end of the mission the game crashed.

I will try disabling the mods that you mentioned and see if the crash persists.
