2.5.1 - Command TransmitMessage displays subtitle for short duration in MP

[Whisper]

Hello,

I stumbled on this bug recently, but I had not set up test on preceding version, so this bug may be there for a while.

When using AI Command TransmitMessage (via LUA script, not tested via ME trigger)) with a subtitle "xxxx" and a subtitleDuration of several seconds (like 30), it's working fine in SP (message is displayed for 30 seconds) but the message is only displayed for a few seconds on MP clients (that have the correct frequency selected, of course), whatever SubtitleDuration is put in the script.

It makes realistic radio system pretty difficult to script :)
