My regular inventory and rock inventory had at least 4 empty item slots in each type of storage. I kept getting a inventory is full message a few times. I had to use the "R" and/or F12 keys a few times to clear the problem for my keyboard or mouse to unfreeze. I was able to save the game, exit and restart without losing data.
