Not compatible with backpacks.

Plugin still works and love it very much! I wanted to report an issue I have come accross recently where any presents/eggs/loot bags can not be opened in the new backpacks added to the game. A chat error says "You do not have enough of this item to open it." but the issue is fixed when the present/egg/loot bag is returned to a player's normal inventory. In addition, the mod is also not compatible with the Backpacks mod either. Curiously, if a present/egg/loot bag is opened in the inventory of the Backpacks plugin, it gives vanilla loot and completely ignores the custom loot tables. 

I will invesitgate this week thank you

Thanks so much for this plugin and all the support, time, and effort you spend on it!
