So I was asking people if they needed free repairs not thinking about the repair bug anymore where when you repair a tool it can go to like -25972 Durability and break at first use.
So I repaired a bunch of items for people and then I noticed I did not gain a single level in repair and I started to wonder what would cause this and that is when I got this bug:

I used approx 40 diamonds to fix does tools to notice I did not get A.. SINGLE.. LEVEL
I calculated what I would have gotten out of fixing all the stuff and it was 5 repair levels, if I could have gotten these levels or my 40 diamonds I lost when this happened that would be great, if not I think you should check out this bug cause I just literally got scammed by the server itself.
