This bug has been declared on 2.1 and now it's spread to the 1.5 branch...
Please take care of this one. My future MP mission are compromised... I ALWAYS fly like this. I can't fly in OA and now if I can't fly in stable, it will be a nightmare.
With my squad we used to meet-up in LAN (20 pilots) twice a year. It's also compromised with this bug.
Again, the same computers (server and client), same LAN, no problem in 1.5.6...
Available, with logs and everything you need.
Thanks a lot.
Goz.
