OK So whenever i load up my ftb (Mindcrack pack) world i get a tonne of lag and only one chunk gets loaded, if i try to walk anywhere outside that chunk i'll slowly fall into the void. I noticed in the crash-log it said something about a ticking entity: enderman but i'm unsure how i can combat the problem.
