Open 1.2.1: FTB Infinity (+GregTech) crash while creating fluxed elctrum

[Macchiavelli]

Version:
1.2.1

What is the bug:
While trying to create fluxed electrum blend, by putting electrum dust (unified by GT) into a fluid transposer (TE) filled with destabilized redstone, my client crashes and i can´t start my world again due to the fact that it also crashes while starting the world. It makes my world completely unplayable


I dont know much about console content, but i could already see that the fluid transposer is causing the problem

Mod & Version:
GregTech 6 (1.7.10-5.06.06) & ThermalExpansion-[1.7.10]4.0.0RC2-129

Can it be repeated:
It should be able to be recreated by adding GT and removing all the mods that cause problems while starting with GT (i.e. TiC, Natura, etc.)

then take electrum dust from GT, a fluid transposer from TE and fill it with destabilzed redstone. It should crash the moment when you put the electrum inside then transposer and try to create fluxed electrum blend

Known Fix:

After some experimenting,I could manage to "solve" the problem by starting the world with TE disabled. This removes the machine that caused the crashes and the problem was gone.
Unfortunately, this also removed my 80 magmatic engines, dozens of resonant machines, and my whole RF-driven energy system collapsed

But my world is playable again
