Whenever I port into a room with illuminated lamps in there, i crash. This does not (seem to) happen when i walk / fly into the room. Note that there is no machinery in the room.

I tested different things, and it happens most often when using an elevator block, and when using a linking book. The crash reports is located here: http://pastebin.com/H06cEmkG

The server is a Direwolf20 server (1.6.4) with pack version 1.0.14 and running MCPC+ as jar.

May have been fixed with commit 3623e72
