Sorry, I "whined" so often about this bug, that I thought it is known.
FG28_Kodiak and me were tinkering around with the mission menu, since it got introduced with the Beta Patch and found that as soon as 5 blue airgroups are active the complete radio menu (tab) breaks on red planes. This only seems to happen on dedicated server enviroment. I used the mission menu too, to give the players the ability to load new mission, request support, replacement and information for players on a dedicated server, but due to this bug, it was meaningless.
Ataros brought the problem to Naryv as you see here:
