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

• Polymorph: polymorph-fabric-0.0.18-1.18.1.jar
• Forge/Fabric: Fabric 0.12.12

Observed Behavior:

When trying to craft an Ender Block from BetterEnd, it has a conflict with the Ender Pearl block from Architect's Pallete Fabric, If I try to choose the Ender Block, the block in the output slot of the crafting table stays an Ender Pearl Block.

Expected Behavior:

Ender Pearl Block changes to Ender Block

Do you have FastBench installed?

No

I do have REI installed, though, if that makes any difference

Just making sure I got this right, you can choose the Ender Block but the output never actually changes right?

Does this still happen if you test this with only Polymorph, BetterEnd, and Architect's Palette installed?

Give me like 10 minutes, I didn't try that because all of those mods are still in BETA and I have to download them manually

I just checked, and yes, it still happens with only those mods and their dependencies installed

Here's the mods I have installed in the test profile.

I've made a bug report on BetterEnd's issue tracker in order to better investigate the issue. Please follow any potential updates there as well.

I've been doing some investigating, and I think this is a niche issue with BetterEnd. Now, I'm not super familiar with their code-base so I could have easily missed something, but it seems like they're doing some non-standard recipe registration and Polymorph does not receive any recipe when it tries to call this when selecting their recipe:

https://github.com/TheIllusiveC4/Polymorph/blob/99fcab89ed59d6b3534c0c40cb03da60b6b3c146/fabric/src/main/java/top/theillusivec4/polymorph/common/network/PolymorphNetwork.java#L36

I'll try to do some more investigating on my end, but for now it seems likely that there is no fix that I can do for this.

This issue should be resolved now as of the latest BCLib release (1.2.3+).
