A new version of Bedrock and Java Edition (Mounts of Mayhem) is rolling out today/soon ( December 9th ): The Sandlot supports Java Edition 1.21.11 clients. The Sandlot supports Bedrock 1.21.131 clients. However, none of the features of the Mounts of Mayhem update will be available until the servers are updated. I will continue to watch for plugin updates and update the servers when possible.

Same for Java 1.21.11 clients. I just looked and the plugin developers released new versions. I'll see what I can do.
My son got bumped up to version 1.121.131 on Bedrock (Xbox) and now gets the error that this version won't let him connect to the server. Is there anything we can do or just wait it out?
Oh, I think they released a new version, @GargoyleAnt said they had the same issue. I’ve updated the plugin that handles Bedrock and it will apply tonight when the server restarts.
