on a test map with lots(!) of mods (including this mod, but i didn't do anything with its items yet besides collecting meat), something had gone wrong, i got several strange effects, and thus i disabled a few other mods. when i tried to load the map again, i got this strange error :

Notice
Error while running on_init: Force already exists
stack traceback:
TheyreMadeOutofMeat/logic/meat-bots.lua:8: in function
<TheyreMadeOutofMeat/logic/meat-bots.lua:4>

since there was something wrong with the map already before i got this error, it might be not this mod's fault, but i found it interesting and thus report it anyway :-)
