Open 1.2.0: Ticking block entity Instant Crash

[ipodtouchdude]

Version:
1.2.0

What is the bug:
Every time I load my world it instantly closes the game. I have no idea how this came about as I was just walking in my world and then the game just closed completely.

Edit: Found out that the Fluid Transposer was instantly crashing it when having a full OpenBlocks Tank in the bottom slot and filling another one in the second top slot.

Mod & Version:

Can it be repeated:
Yes

Edit: If you put an empty OpenBlocks Tank into an empty Fluid Transposer it will crash the game and you will have to use NBTExplorer to fix the game save.

Known Fix:
Open save with NBTExplorer and deleting the Tank out of the top slot.

Fixed it, it is a Thermal Expansion bug with the Fluid Transposer and OpenBlocks Tank.

I am able to make this happen using a hardened portable tank from Thermal Expansion itself.
Suggest tagging this topic with [Corrupts World]. Its already happened twice on the server I am running.

Do note the fluid transposer must be powered for this to happen.
