Hi good day,
Just registered to say , it happens the same to me with the infinite movement screen.
I am in a terror mission in "el cairo" and after some turns i get infinite mov screen.
It happened to me maybe in the 3rd turn, but after reloading the autosave was able to bypass it until i got it again maybe 3 or 2 turns later and wasnt able to bypass it.
i have steam version.
