Happened when @Darkosto was in the end. Dunno if it has anything to do with it.

Likely related to #509 and #532

Other report from someone after joining world:

We came across this today; it was a reoccurring crash

Crash here: http://pastebin.com/gbexux79

Playing with RS Beta 5 on FML 2116. Player just left the end, teleporting into their base

Tried builds 451 and 455; both crashed with java.lang.NoSuchFieldError: VARINT

EDIT: Ended up going into MCEdit and fixing the ticking block
