When ever I load a save (recreated in a test world and same issue) with a buildcraft waterproof pipe connected to a dynamic tank, the pipe is flipped. You break the pipes to relay them and most times works, other times it causes a crash. Briefly upgrading to 1.3.13 and same issue with the buildcraft pipes exists.

You see me warp to another area of the map, the old cave home to sort out the pipe there. When I get back to the main base, the pipes have flipped again.
