[andryqx]

Environment

Minecraft version(1.12.2/1.16.5/1.18.2): 1.16.5 Build version(Get from /version command): 1.16.5-98eabb0e Mods/Plugins: Polymorph

Describe the bug The Polymorph mod (can prevent crate conflicts) does not work. There is no button that would help change the result of the craft as in the attached screenshot.

Expected behavior Everything should work as in the screenshot, the button should appear when crafting in the workbench

To Reproduce Just download Polymorph mod and test it on CatServer. It shouldn't work like that. It just not working

Screenshot/Video (that mod have to work like that)

I agree with the problem above. I would like to note that errors are corrected for a very long time and there is a need to change the server core.
