So I loaded my world up after you fixed the upgrade crash, and uh, this happened.

Data did not get saved-Loaded corretly. Did a replace fix it?

Seemed to. I can only presume that because the world crashed shortly after I placed it down it broke.

Nope. The Reason why it did not save its data because the world did crash at the point where you put in the Modul. So it the data got never saved... ^^" Well at least it is nothing to fix anymore..

Yeah reason was because it try to check which upgrades which valid which caused a crash because of the wrong class i did call (i hate scala for that) that is fixed....

It didn't crash when I placed it, it crashed when I put the redstone inverter upgrade in the induction furnace next to it :P
