Hello. When I tried out this plugin, I thought it didn't do anything on my server at first. As it turns out, it's just the thing I was testing that didn't work. Most aspects of this plugin work fine for me. I can craft enchanted golden apples, prevent off-hand usage, etc. But, I cannot revert the damage of tools and swords. There are no errors in the console.

Spigot Version: 1.12.2 #131
OldCombatMechanics Version: 1.6.3
Config: https://pastebin.com/Qjrsv1vC
(I also tried defining worlds, but that didn't really affect anything, and other things worked without defining worlds)

Please note that I was not looking at the damage displayed on the items, I was actually hitting mobs and comparing damage.

Thank you for the response! These are the messages when using (unenchanted) stone swords/axes:

Please turn on debug mode in the config and check the messages that are sent when you use a weapon

And is the damage displayed after "New Damage:" the damage you find is being inflicted (in half hearts)?

At the time that I posted, no. I don't remember the exact numbers, but I did check against the debug message, and it was off by at least a heart. When I checked again just now, it seems to be working. This was something on my end, I guess. I'm not really sure what made it start working, but I'm glad it did. I am sorry for posting an issue that was server-specific, and not anything you could fix.

Thank you very much for your responses, and politeness.
