So I just got my first ME system, but it's being a bit weird shift-clicking into a terminal and out of the crafting terminal... When I was putting all my items into my drive of 1ks by shift clicking from my inventory into the terminal, it only moved about 6 stacks or so at once, so took multiple clicks to empty my inventory. (and my drives still have space, didn't run out of space)
Then shift-click crafting coal blocks only makes 22 blocks at a time, then only 3 coal is left in the crafting grid along the top side. So for some reason it stops properly re-populating the grid after the 22nd block... If I craft one at a time, it always restocks properly. (and there's over 3k coal in my drives)
*edit* I'll just try the new AE, beta 22, and see if it helps...
