Ok, so this is related I think to the original post.
I log into a MP server, another player has a mig-21bis, he can choose any armament he wants for his a/c. I can choose some but not all, for example r3r, R-60m no problem.
When I try to pick fuel pods, aso and a few others the box appears to indicate that there are none at the base. Also I can see s-5 rockets on the list but when I pick the to load on ground crew reports copy, then re-arming complete but nothing shows up on the pylons.
This is the case for most MP servers, not all though. Everything works fine SP, I have tried all ways to contact ground crew ( \ key, tab then f8, and oft switch) I have tried to rearm with engines running, engines off, elec power on/off. I am out of ideas. Any suggestions?
