SendChatMessage calls can be ignored when not waiting between calls

[Fort-TM]

If you call SendChatMessage successively without sleeping between calls, one of the messages won't be sent ingame. Something like

BetterChat::SendChatMessage("First message");
BetterChat::SendChatMessage("Second message");

the first message won't be sent. Adding sleep(200) between calls works, but I haven't seen this being mentioned anywhere
