i'm still having the issue with duped chat messages. everything I have is from the newest branch and recompiled etc.
but when I set irc_chat_relaytype 2 (all in-game messages to private channel), I still get the dupes. But if I set it to 1, I'll only get a single message in the public channel.
I are confused, just turned it off for now.
*edit*
oops, was just because I was using the same private channel in tf.cfg
