One more here.
I tried to enter Contention 80 now, and, after choosing the coalition, everything freezes. This is because, the DCS, at this moment, has to load the entire F10 map with all the units that the team has on the map. This is impractical.
(At this moment the DCS freezes and I cannot select the slot)
In the GS server, which does not have ground units, I had no problem.
