patch to allow the mod to load on 1.21.1 versions 1.21.2 and onwards break the mixins, will likely require a third jar and code updates to support there is no 1.20.1-1.20.4 jar for this version since it is exactly the same except for the version bump

there was a build 0.4.2 that had broken air control, it is no longer available but servers should check for version ID 8 to prevent it from being used. this new build is version ID 9
