Minecraft Version

1.21.3

Discord-MC-Chat Version

2.3.4

Description

The moment I get an advancement the server crashes. When the server starts again I have the advancement, but the server crashing every time is annoying. Also, when I get an advancement that I already have had before (by using /advancement revoke) instead I get kicked, and the server stays running. Also, in the log and config files I have replaced a few things with . Also also, as you can see in my config file, I tried removing stuff from the advancement message, but that didn't work either.

To Reproduce

Join a server that has the mod installed on 1.21.3, version 2.3.4 (and has a properly set up Discord bot).
Get an advancement that shows up in chat.
Observe that the server crashes.

How to only get kicked instead of crashing the server:

Join a server that has the mod installed on 1.21.3, version 2.3.4 (and has a properly set up Discord bot).
Get an advancement that shows up in chat.
Start the server again and join it.
Use /advancement revoke to revoke the advancement you already have.
Get that advancement again.
Observe the different kicking message.
Observe that the server is still running, and you can easily re-join it.
