Ian, is it, to your knowledge, at all possible that when the cvar to disable living <> dead teamchat is on, teamchat isn't usable at all?
The command itself is still available but no messages are printed from what I can see and I've asked if anyone else could read it, but no.
I also don't see any other plugins that would (have reason to) interfere with teamchat, though I do have AMM installed. If that's of any significance.
ac_teamchat was 0 first but then I noticed the bug and put it on 1. Teamchat still doesn't seem to work.
PS. Colours don't seem to work for me either but that's fine with me cos I'm not too fond of it and AMM uses coloured chat anyway. (as in, different than yellow)
