Maybe you've used other mods besides ?I'd met the same situation when trying Sins Mod The bosses ran away from me!So i am confusion.
why do i overload brain of cthulhu on eternity mode
and they literally all run away from me?
i know i'm strong, but god damn i've never had a boss, let alone multiple bosses run away in sheer terror
they all despawned after they got too far.
Or please try again,that might be a mistake
After all,how fun it is~
