This happened to me twice now: A mission would not resolve after every enemy was killed. I even spent 10-20 turns combing through the entire map, every room in every building, to no avail.
The only mission goal listed is “Kill all enemies.”
There are definitely no more enemies left on the map.
The mission does not end.
Ending the mission by evacuation will count as mission failure, with no rewards gained.
So is this like when you finish the battle and it gets to the screen that shows who got injured and promoted? that’s where it locks up for me, when ever I try to move on it doesn’t let me get back to the geoscape I click the button and it just sits there forcing me to goto task manager and close out the whole game will what you mentioned fix this issue?
