Despawning issue? you mean the issue where mobs remain on the map during the day time? If that's what you meant then I just put it on peaceful, then went into creative and spawned Slendy using the creepypasta mod
I haven't noticed that problem, I do know they despawn in the daytime, but I haven't noticed at night, maybe they just teleport to another place far away?
no I made it as a single player map so you can lan it, my internet connection is not good enough to run it on a multiplayer server. I can still send it to you though
