Groundhog Day play

I did do the f10 reporting on this, but wonder if any of you experienced this?

My Tiamat first attacks the infeasted aircraft. Then when I go and complete the ground mission, I was returned to the same spot and upon return to Geoscope, I was put at the same time/spot before the mission I did this twice. On my 3rd Try, the screen froze at Return to Geoscape. I cannot progress the game.

any hints would be greatly appreciated!

Work around, I flew Tiamat to another base, then flew it back to the infestation…Game now progressing.

Try looking at this.
