Versions:

• Polymorph: 1.16.3-0.16
• Forge/Fabric: 1.16.3 - 34.1.42

Refined Storage - v 1.9.9

Crafting Station - v 4.1.1

I believe these are fixed in more updated Polymorph versions. I see that you're on 1.16.3, but I believe Polymorph 0.18 should still work on that version. Could you try that and verify for me?

It is indeed fixed on Polymorph 0.18 on 1.16.3.

Thanks!
