My friend and I download a few mods to play on his server. They were: Treecapitator, bspkrsCore, CodeChickenLib, ChickenChunks, NotEnoughItems, MobStatues, InventoryTweaks, ironchest, Baubles, journeymap, and Advent of Ascension. When we play on singleplayer, the AoA mobs spawn. A lot. But as soon as we go on his private server, none of the AoA mobs spawn. Vanilla mobs such as Creepers and sheep still spawn, and nei still registers all the AoA items, and the AoA gui is still on the screen. It's just none of the mobs spawn. Help, please?
