Bug: When opening the inventory, an object's inventory is also opened, not closable, and can't be interacted with.
Steps to reproduce:
1) Right-click an object that has an inventory.
2) Look in inventory
3) Right click an item within the object inventory.
4) Message along the lines of "You can't do anything with that" occurs.
5) Close inventory, walk away.
6) Open player inventory, the object inventory is now stuck and bugged. (If you right click an item in this bugged inventory, the game will crash)
