Description: When attempting to add a protection enchantment token to my boots, I receive this client crash as soon as I place them both beside each other in any crafting grid. I haven't tested with other tokens/tools yet.

Looks like Mojang changed the visibility on that method for reasons I can't even imagine. I'll look for a workaround.

I couldn't reproduce this for some reason, but I've got a temporary fix that should be compatible with 1.11 and 1.11.2. Might be a day or two until I get a new version up, I've got a couple things I'm currently working on.

The new release seems to have fixed it :)
