I have a huge Problem with my Modpack, then whenever I build an Item its missing 1-2 Durability, and because of that reason, I can't build any Machine, which uses a Pickaxe or any other Tool.
I already tried to remove all Configs, then the Problem is no longer existent, for the Time being, but after a Restart the Problem is back there.
I really don't know what else to try and would appreciate any Help or Solution ideas.
The Modpack is here: https://www.curseforge.com/minecraft/modpacks/minecraft-extended-world
I found the Problem, it was the Mod: Omni's Aged Aether Blocks
