When running on Minecraft 1.20.4 with version 3.2.2 of this mod and any version of viaversion installed on the server, Modded (Fabric) 1.20.5 and 1.20.6 clients are unable to connect due to a mismatch between registry data. Vanilla clients are unaffected.

I've reported this to the viaversion team and they said it's currently an issue with any mod that may send out "minecraft" registry data.

It's also been reported on their github, but I figured I'd create an issue here as well so you are aware of the issue.

Here is a snippit of a log from clientside showing the issue: https://mclo.gs/0DuYL8O

Already aware via this issue meaning this is technically a duplicate.

Fixed.
