I'm finding that the rubber trees and the custom axes (ruby, emerald, sapphire, etc) are not working properly.

The guys at MCMMO took a brief look at your code and said that the axes in the custom file are not registering as axes therefore taking extra damage and breaking on use after a few uses due to improper tool types.

The rubber tree and other wood blocks are not properly registering as tree blocks as well even tho they are in the config file as wood and therefore not breaking properly when hit with anything. They are leveling up woodcutting skill with MCMMO though but they do not break properly as they should with other tree blocks.

Thanks

I'd be interested in knowing how you were able to add custom wood to the config, where I just added the possibility to do so? :)

This should work now. Add IDs that match on your server, they will probably differ from the default values.
