Good to know about — if it happens again, try to grab a crash log and I'll see if I can get a fix in.

Hey sorry for the late response I went off to bed shortly after posting the thread. Here's the crash log :). I know it's the crucible relic specifically for 2 reasons: 1. I removed the crucible relic and then removed the card and it didn't crash. 2. The crash log itself seems to provide evidence of that. I should also mention that this is through the Toke method at a campsite. IIRC it does happen at the merchant removal service too though.

Game crashed.

I just did some more testing and it's only Crucible (Reliquary) + Peace Pipe (Vanilla) causing the crash

Yikes! I'll have a look at this.

Alright, this should be fixed. Thanks for finding an easier reproduction!
