Bug description

console Repeated warnings

Please link me the CatServer software source, as it seems like this software doing a bad thing as like Mohist. Until that I can not do anything to fix it.

请将 CatServer 软件源链接给我，因为看起来这个软件像墨家一样在做坏事。在那之前，我无法做任何事情来修复它。

https://github.com/Luohuayu/CatServer

As I thought, this software is also removing or making it unvisible the constructor that TL needs it. Now, I am ask a question: How do I fix this? Plus, I see 0.5 activity on CatServer issues, so sometimes the author answers to an issue that was created 1-2 months ago.

So I suggest to you: Switch to Mohist server, or report an issue to CatServer with title missing/unvisible constructor in PacketPlayOutScoreboardTeam class
or idk

所以我建议你：切换到Mohist服务器，或者用titlemissing/unvisible constructor in PacketPlayOutScoreboardTeam class 或idk向CatServer报告问题

ok

Closing this issue now. I can not do anything in my side to fix this issue. The only way to remove that NullPointerException is to make a fail-fast or just a notnull condition and warn the user about this, but it makes no sense to do this.
