This is a freak of a bug that will be near impossible to replicate:
- Chinook arrives at a crash site, engage mission.
- This occurs at the same time that interceptors auto-engage a UFO
- The game tries to run both combats at the same time, rabidly eating computer resources
- The air combat shows as the black background in the ground combat, and as the black background in the uppermost part of the geoscape
- Even though you can see the air combat screen, and it is active, you cannot interact with it by mouse, only keyboard
I got out of this jam by:
- Finishing the ground combat
- At this point, you cannot advance time, even at the base game speed
- In the Geoscape, pressed [sPACE] and prayed that my F-17s didn't die
- Game and computer resources returned to normal, and all Xenonauts lived to fight another day
Sorry, but I didn't have the presence of mind to get a screen capture.
