I implemented a mock forest driver and found a problem in using the singleton design pattern for InventoryManager. When two instances of FilePlayerDAO were instantiated, inventory was reloaded from the players.dat file. I had to check to see if the player had inventory before loading all data from players.dat. It's dirty, but it works... I'm starting to wonder if an inventoryDAO would be best
