I can confirm I've had the same 'play M-4 tank brigade' error twice, as well as just getting kicked from the server repeatedly in the enhanced wingman main. There's also extreme lagginess in the message buffer at times, and I was awarded way too many (32000) points for killing a human players ground vehicle one time. So yes, there are some issues with the system. The discos are also occurring in the regular main, though Ive not seen the M4 Tank Brigade error there.
I hope this doesn't carry over to the s3, it definitely needs some more testing.
Same point thing when I shot down a bomber flown by a player, got 32k points. But in contrary, when I managed to shoot down a player-flown fighter with JU88s peashooter pilot gun, buffer showed the kill, server kicked me (once again) out and when I checked later, scores show it was me who got got killed by him and he got 250 points...
The sim itself is nice and enjoyable to fly, points are not big thing but these constant discos are extremely annoying. What happens, if server kicks a pilot out in a middle of S3 or smt similar? Can he rejoin from where he was thrown out or how (if at all) continue?
