This update brings a new experimental feature: a repair command. You can use
/oraxen repair to repair a item in your hand or
/oraxen repair all to repair all your items. It supports Oraxen and vanilla items (it is configurable).
You don't need to reset your configuration, just drag and drop the new jar. I'm working on a fix for shields but I got some problems with it, I expect to get it working soon.
