Experiencing the same issue as ramavich, however I'm not using the 'WeMod' version, but the normal .exe one. They seem to die whenever they go rest after returning, if the cheat is deactivated. I've tried forcing them to rest with it activated, then deactivating it, and they still die after resting.
I've tried disabling before saving vs having it enabled at save, no difference in how it seems to work.
