so i noticed this thing today.... when someone is in the area of the beneath where i spawn, the mobs from the beneath also appear in the overworld. i cant kill them in the overworld but they can harm me. i can also see the players in the beneath from my side. this goes reverse as well.
heh that is odd, also by beneath do you mean deep dark, or this a totally different mod i haven't heard of?
Deep dark is from Extra Utilities, The Beneath while very similar is a separate mod that was basically made as an alternative to the Deep Dark while Ex.U was still been updated to 1.10.2, the main difference been that The Beneath has a number of configurable options and features that make a lot of people prefer it, which is why the Deep dark is actually disabled by the modpack devs on SF3 in favour of The Beneath.
