Well, windows is not available. I'll try the windows build with proton or wine when possible. Also, Unity is now in beta (2020.2 something). Which version are you using?
Just played a little more and noticed another issue: while playing, in map view, clicking in the menu (ESC key) will also drop paratroopers. For example try to set vertical sync. By the way, how can I set vertical sync on by default instead of toggling it all the time?
Thanks a lot for the reply!
