Versions (Be specific, do not write "latest"):

• Polymorph: v0.0.12
• Fabric: v0.11.7

Observed Behavior:

1. I constantly see recipes that shouldn't be there, in my case it's tin nugget that can't be crafted in the current situation
   
2. When choosing a recipe, the panel is visually duplicated and it looks strange
   
3. When melting, you cannot choose the final result, it will always be the same.
   It looks like this bug: #87
4. The crafting menu is displayed below the items from the REI

Which version of Fabric API are you using? Have you updated to the latest?

I try to update all mods to the current version, and fabric-api are no exception.

fabric-api-0.40.1+1.16.jar

Which version of Fabric API are you using? Have you updated to the latest?

Okay, hand me your mod list then. Make sure you delete any mods that are not involved in the issue so that I have a minimal workspace to look at.

Also, I have confirmed 2 and 4 and am working on solutions for those.

I cannot reproduce 1 and 3, so I will need more information such as the specific recipes/mods involved.

Do you need to drop only links to curseforge or upload archive with all the mods?

I need the version numbers also, so you can just list out the mod names and their version numbers. Also, I want to re-iterate, not all of the mods, just the ones involved. So, Polymorph, Fabric API, and I see Tech Reborn in your example. Maybe one or two more mods if their recipes are also involved. If it's more than 5 mods, you need to trim it down.

I use 72 mods, and I don't know which one is causing the bug. Finding a mod that causes a bug will be very difficult.

UPD: I spent a huge amount of time to figure this out, but in the end I found mods that cause bugs.
I think that at least one bug occurs due to the better-nether-5.0.7.jar mod

Thank you very much for your cooperation, I'll review everything later on and report back with an update as soon as I can.

Okay, I understand what's happening in 1 now. I have working solutions for 1, 2, and 4. Still reviewing 3.

All should be fixed in 0.0.13. Thank you for reporting these issues.

Thank you, I'm glad you responded quickly.
