Does the Flatpak not yet include Episode 4? Or if it does, how do you start it?
I finished Episodes 1-3 and the EDF and holiday missions, then looped back and replayed a few missions because I missed some secrets. But now there is no way to start Episode 4.
Selecting only Episode 4, in the mission filters, shows only the AMC Vehicle Testing Site, New LA and Sector 14B as visitable locations, and the air bases and satellites as hoverable, but nothing else.
Great game, by the way. Far more content than I initially expected. And awesome music on many of the maps.
