Describe the bug

When I'm trying to launch my instance, I get this message:
Error launching Minecraft: No loader version selected for neoforge.

In the instance settings, I get this: "neoforge is not available for Minecraft 1.21.1. Try another mod loader."
Only available versions of MC for NeoForge are 1.20.1 and 1.21.10

Yesterday everything worked fine. Automatic repairing didn't help.

Not really anything we can do on our end at this stage, but we plan to mirror their metadata to prevent this from happening in the future.
