Sometimes when I have my inventory open, click a hot bar slot, then click an empty inventory space to make that hot bar slot empty, then I close my inventory and reopen it, the item I removed from the hot bar has completely and irrecoverably disappeared from my inventory and the entire game. Whether it was a tool or stack of blocks or anything else. All are susceptible. Does not happen every time obviously or there would be outrage. Usually I've walked around a bit and probably picked up something else before I open my inventory again to find that my item has vanished. My inventory is not full during any of this. I have had this happen many times.

This issue feels new with MCPE 1.1.5. I don't recall noticing it on the few previous versions.
