I had a player report a bug on my 1.17.1 server today where i have the LevelZ mod and Universal Graves installed. i also reproduced this myself. You just need to have one of the armors that are "locked" behind a LevelZ skill in your inventory. Die and go to collect your grave. When you go to use the new Shift+Click to get everything back fast, the armor is getting auto-equipped and is able to be used although the player should not be able to access it yet.

I'm unsure if this was a LevelZ issue or not since before the new Shift+Click was introduced, this wasn't an issue. I wanted to bring it to your attention.

Thank you for the reply! Awesome! I look forward to updating, thank you for addressing this 😄

I'm going to fix that in next big release (week or two, depends how fast it will go)

Should be fixed in latest beta
