Adding an enchantment to Draconic tools through the item GUI causes the client to crash when exiting the GUI. Enchants stick when reloading the world. Haven't yet tested Wyvern tools.

That seems to be related to another crash i am already investigating. I hope to have a fix out soon.

I get the exact same crash report when I attempt to open up the tool configuration screen while my character is moving.

Indeed, further experimenting has revealed that the GUI just likes to crash...a lot. Let me know if there's anything I can do to help test. I bloody love the work you've done with this mod.

im having the same issue only does it on mp server, single player it works fine, and i get the same error report

This crash is fixed in snapshot 4
