Cannot join server with 1.17.1
I am Japanese and use a translator, so my sentences may be strange. A problem arose.
I recently received notification of an update to this plugin and immediately installed it and installed it on my Minecraft server. However, I can no longer connect to the server. The version is 1.17.1 I used MythicDungeons-1.1.0.
Here is the error log of the server.
[io.netty.channel.DefaultChannelPipeline] An exceptionCaught() event was fired, and it reached at the tail of the pipeline.
