I found several post regarding this issue, but none of them had a fix solution.

I played regular game and already passed January with no issue, got 5 bases and plenty of experienced soldiers.

I then make a few weeks play through without save until another wave of UFO shows up, mostly Bomber with escorts. Finished the waves with 1 scout and 1 Transport on ground and sent 2 teams on each site.

When the first team reached the Transport, the game goes to the ground mission loading screen and it just stuck at 80% forever.. the music still playing, the mouse is moving, and you can hear click sound when the mouse is hovering on some place.

I cannot alt+tab since it will always return to the loading screen. I also can peek the task manager and it shows very high power consumption on xenonauts.exe.

I tried to restart and reload the autosave, and it always stuck on the same screen.

Is there are solution for this issue beside reloading the earliest save file?

Cheers,
