I randomly mutated and got the trait “thinned skin” while killing everything in a fema camp. Also when I open up the craft menu MOST OF THE TIME it still crash.
Chances are the mutation is from radiation.
Also, Might want to put this in the Garage, considering this is the wrong section.
There is a bug report about that crash on github: https://github.com/CleverRaven/Cataclysm-DDA/issues/8763 (I assume it’s the same bug). There is also a PR that fixes it in the queue.
