I noticed that recently in the TARDIS dimension, I am having intermittent FPS tanks that were not occuring before. I've tried relogging, restarting my computer and lowering my graphics to the minimum, but nothing is working. Is it possible that someone perhaps has something could cause a lot of lag in the TARDIS dimension? 

Could you tell me the coords? There was a duplication bug a while back in the TARDIS dimension which has caused a lot of entities to get stuck in some TARDISes

 The first time I noticed it, I was at X: 653, Z: -1152, which is one of the hallways of my TARDIS. I did notice that it was still happening in other people's TARDISes, too. Today, I've logged on and the random FPS tanks seem to be gone for now, but I'm assuming that you would still like to check the place out on the off-chance that maybe there is a dupe bug somewhere.
