Same error, my own fualt, but here is a little more detail for your trouble shooting pleasure.

I put four ore blocks unstacked in a forge with the liquidy stuff I thought I needed and got a message that I couldn't combine these types, so (in the forge) i stacked the four up and hit combine again, and of course was told that item have to be unstacked. It was then that I tried to pick up the stack of four and put it back in my bag with the other blocks, but I noticed the stack was one short. It was 17 before I started and after pulling out of the forge it was 16. I didn't mind and moved on, after zoning I had 13 blocks on my curser and none in my bag, I lost the four that went into the forge after zoning, but only had lost one that went into the forge at the time of removal.

Strange, but meh. I'll be more careful next time.
