Hi, I have a small problem. I went into the 80's tardis and entered flight mode in the tardis dimension. All was well and good until I tried to exit. Then I couldn't land. On anything. I tried falling out of the world( -10000 blocks down as writing this ) teleporting out ( nope) teleporting to another player (nein) pressing shift (nyet) trying to land on tardis blocks (non). Tried everything plausible and at (11000) blocks now. Am on private server, please help me!
