i gave a block entity entityInfo.inventory(5,1); to mimic a hopper, but the inventory still shows up with 9 slots in the row. when I tried to put an item in one of the 'extra' slots, the game crashed with an indexOutOfBounds exception. then, i curiously tried making a 12 by 1 inventory. it instead made a two-rowed, nine-column inventory. this time, no slots seemed to crash the game. the second problem isn't too bad, but the first kinda is.
