The thermal expansion Cache (Basic), once placed and used, can not be broken by any means. Even going to creative mode and attempting to break them does nothing. Amusingly enough, they can still be pushed around via pistons. There was a recent modpack update that seems to have broken large steam generators and made them unusable. Prior to the update, I was able to use a large steam turbine to generate power, although at a reduced efficiency, as it did not have 100% of the steam it needed to operate at peak power. I've since upgraded to two large steel and two titanium boilers and I still can't push enough steam to it to power the turbine. I'm using the elite mechanical pipes from the mekanism mod and I just can't seem to get it to run. Steam outputs from the boilers are 3700mb x2, and 1600mb x2... Any suggestions on how to fix either of these?
