I'm thinking of doing a mob farm system sort of like what Monkey Farm has in his world, a giant tower that drops the mobs into a 2x1 area. Since Mo Creatures is not part of FTB, and I do not think it is on the list to be added, this creation should still work, correct? Secondly, if I put up an obsidian tube to suck up the drops, or the machine to picks up drops (forgot the name, extractor?) will it pick up the drops AND the XP orbs and destroy them, or just the drops? If not, is there a mod that will auto stack XP into certain increments like items currently do, say in increments of 50 orbs (it can be done, as the dragon drops orbs of different sizes) to reduce lag on servers/from mob farms?
