Currently playing Better Minecraft Forge 1.17.1 and every time i join my game i get another set of hiking gear when i don't have a set on me.

I feel like this issue has been solved internally.
we'll try and put a new version out soon

Solution : release new version

I have the same problem, but I get another set of hiking gear even though I'm still wearing the set I got after I generated the world (side question - is it meant to not break easily? I received tons of damage and yet the set is only half-broken)
