Some messages throw an exception since the 1.20.4 update (3.7.0)

[Nanpure]

Updated Paper Spigot. VentureChat 3.7.0. Clean server.

Type in chat: 1.20.4

The chat disappears into the ether and is not visible to yourself or other players. The plugin also throws an exception in the log:

Confirming the same on my end. Mostly affects messages over Velocity - not sure if it's the same or different issue, but all chats regardless of bungeecord setting, permission, or even range show up as duplicated in vanilla chat on the non-origin servers. Everything otherwise seems to look normal on the origin server (range and permission are respected, chats aren't duplicated). https://gist.github.com/mercurialmusic/926f771cc1dc1f2d824d969635dc3c69

Using VentureChat 3.7.0 on git-Paper-381 (MC: 1.20.4) with ProtocolLib b679 and Velocity 3.3.0-SNAPSHOT (git-408b420a-b316).

This seems to be fixed in 3.7.1. We've deployed this version and everything seems to be working great so far.

@mercurialmusic can you confirm whether or not you're still having problems?

[mercurialmusic]

Thanks for the heads up. I haven't been able to test again yet, but am somewhat wary/weary after spending an hour on it yesterday for it to fail. Will probably wait a bit before trying again and can do a new issue if mine persists.

@mercurialmusic I'm closing this because it solves my reported issue. Please open a new issue if you continue to have problems in your testing.
