The HedgeWitch armor renders invisible. I'm not sure what is causing it, I do have a few mods that affect rendering like sodium and indium, I've tried disabling every mod I know of that affects rendering to no avail. I haven't tested with the other witch armors but I imagine it's the same. I'm using version 1.18-15 of the mod and this is the modpack I'm using https://drive.google.com/file/d/16lum5SmoefIH3v_pWkQa4OH8HN-T652E/view?usp=sharing
Drive link because I built the modpack myself

Update: Alchemist and Besmirched armor also renders invisable

Does it still happen in 1.18.2?

Not sure, Can't update to 1.18.2 yet since most of the mods I want in my modpack are still in 1.18.1

I'll close this then as I can't reproduce it on the current latest version (1.18-16). You can reopen the issue if you find what mod causes it
