Your Expectation

Had a stack of universal fluid cells, took some of them and filled them with molten polyethylene to move to a machine, then tried to return the now-empty cells to the same stack as the rest

The Reality

The cells I used didn't stack with the old ones. Using /mt hand on both of them makes it look like an nbt tag issue - the newly-crafted ones are IC2:ItemFluidCell but the ones that have been used and then emptied are IC2:ItemFluidCell.withTag({})

Your Proposal

Adjust universal fluid cells so they have consistent NBT data when freshly crafted and when being emptied after holding fluid.
