Hello, I'm the Developer of the TreeAssist plugin. I've been getting many requests to make TreeAssist work with Tekkit, and I can't figure out what my issue is for the life of me.
The server throws this error whenever a player cuts down a tree, and kicks the player. When they rejoin, the plugin has run (seemingly) fine and the tree is cut down.
If anyone has any idea what could be causing this, common things to look for when making something tekkit compatible, or any other help, it would be much appreciated. Here is the whole class if anyone cares to see it.
