This morning, I installed v2,1,1 on my 1,19.3 Fabric instance. After playing for a while, I noticed something strange: the Configuration button is now missing from Mod Menu!

For demonstration, here's some screenshots with Cull Less Leaves, which uses Yet Another Config Lib.
Here's what we got with the previous version of YACL:

And here's what we get with the latest version of YACL:

As you can see, the configuration button for Cull Less Leaves is now gone. I don't think I need to explain why this is kinda unhelpful.

I have confirmed that the only thing that changed was YACL. Nothing else changed. I also rolled back and re-updated my version of YACL and the results are consistent.

Not sure if this is relevant, but just in case, the version of Mod Menu I'm using is v5.0.2.

Did a little more poking around in my mod stack, because I could have sworn I had another mod that uses YACL. Turns out I did: Zoomify! I only just now realized you are also the author of Zoomify. Neato!

Anyway, with v2.1.1 of YACL installed, here's what I'm getting for Zoomify in Mod Menu:

The fact that this bug also seems to be affecting Zoomify suggests to me (although this is still a guess) that YACL is at fault, rather than the mods that (try to) use YACL.

The buttons have returned with the latest updates to Cull Less Leaves and Zoomify.

Uhhhhh, what the heck are you saying??

First, this issue is closed as completed. This issue was fixed back in December.

Secondly, no one needs a fix for 1.19.2. Just update to the latest version of the game. New versions of Zoomify and YACL are available for 1.19.4.

Third, this issue was opened about an issue with a small incompatibility between Zoomify and a new version of YACL. The problem was fixed by updating Zoomify to be compatible with the new structure of YACL. This issue was NOT, and has never been about asking for 1.19.2 support. When I opened this issue, I was already playing on 1.19.3 for Pete's sake!

If you want to ask for 1.19.2 support, OPEN A NEW ISSUE FOR IT, because that request is COMPLETELY UNRELATED TO THIS ISSUE.
