I don't know if it is intentional, but in older versions we were able to use ChatPlayer from server side just fine. Now, if you call it crom server, clients will have the following in their script.log and no message will be shown
SCRIPT : Chat: Unknown channel 0
Call ChatPlayer from server when being connected on it, then check your client script.log (and the fact that there is no message popping up)
Can you show code how do you calling it, because since last update in function ChatPlayer there is no option select channel, only text
GetGame().ChatPlayer("foo");Anywhere serverside, this will errors out the said message for connected clients.
