I was going to start a new world and wanted to adjust the durability of the netherite tools I installed the mod menu mod (which is under compatible mods) and changed the durability to 5000 as a test but when I reentered my world i found that the durability was the same (yes i did save&quit) even after grabbing new netherite tools (how much armor the elytra gives didn't change either) I'm not sure how to reproduce this bug.

Alright for some reason it works now
