Awesome plugin!

There is one problem.
If you put anything under the Ammunition category it will not run.
As you do a check in Init called FixHeavyCategory. 
There is a problem there, because you do a foreach in a dictionary and overwrite it at same time.

Thanks! I uploaded a fix for this issue along with a few minor improvements. Glad you enjoy the plugin! If you'd like, I'd be happy to advertise your server on our github if you share the details with me.
