Have an NPC wear a sheath or a large quiver. Attempt removal of the said gear from the NPC armor layering menu by hitting ‘u’. Should crash the game for either item after hitting ‘y’ for confirmation. I could repeat this maybe 5 out of 6 times for the quiver. No idea why it DIDN’T crash the one time. Couldn’t repeat that. Whether the NPC was carrying a knife, bow or arrows at the time didn’t seem to matter. The NPC had plenty of storage space, so I don’t think this is about that either.
