This seems to only happen when A player enters the twilight, this is on a freshly generated world.
Is there anyway to fix this? In console this shows up as

seems like MCPC doesn't understand twillight forest creatures. I can only suggest you sumbit to MCPC as its an MCPC problem. I haven't been around for a bit, but last time i was on FTB's stand was they didn't offer support for MCPC issues.

Personal I would drop MCPC and use mystcraft to have multiple worlds.
