I'm having the same issue, about 10 minutes in I experience this and there doesn't appear to be anything I can do about it
Edit: here is the exact error message
Error while running event factorioplus::on_character_corpse_expired (ID 91)
factorioplus/body-finder.lua:24: bad argument #1 of 2 to 'pairs' (table expected, got nil)
stack traceback:

Did you add this mod during an existing game, or in a new game?
This could be an error of adding the mod when you have a corpse already on the map, so I'll look into fixing it!
