So I downloaded some mods from the rorum and the activated them, and poof! my game crashed, so I removed them from the mod file and while doing so removed the core file as well. now i have put the core file back in but stupid rimworld wont activate the core stuff by default and for reasons unknow now if I redownload rimworld it does it there too! is there a way to reset the rimworld files ? without opening up rimworld itself?
