Really basic, the new chat system is extremely buggy and doesn’t work half the time.
For example, I as a DDA member once managed to see AA’s team chat, which clearly isn’t meant to happen. Then there are also cases where some DDA do not have access to teamchats they are meant to, while others do. For example, if hostiles are authorized we get combative. There is a chance that a DDA member doesn’t get combative at all even if they rejoin. Same with the hostile team chat, we sometimes just never get it.
Plus then we have the bug where you can just see combative, enforcement and specu chat randomly, defeating the point of having those chats.
Tldr: Revert the chat system back to the system that actually worked
