By Design Vanilla Repair dosn´t work.

[Freizeitsoldat]

Hello.

I have a shovel with Eff 4 , Mending and unbreakable 3. Normally i can repair it for 9 levels, at the anvil, as long its still yellow.
As it switches to red it will cost 17 levels ... so far, so good.
But as i want to repair, i will loose 17 levels and its still red and i will get my normal diamond shovel backk too ...

So its not repairing, i will loose 17 levels and that´s pretty shitty

use the gos repair anvil, the only thing vanilla anvils should be used for are adding tomes to your utilities
