I killed an Arthron and then mind controlled the resulting Umbra. Unfortunately, I evacuated all of my operatives before ‘releasing’ the mind control. I was left with an unwounded Umbra wandering the map with nothing attacking it and no way to end the scenario/mission. Further, I was forced to use the Control Panel to terminate the process. Big Surprise!
This is definitely wrong… Did you F10 it? (it’s good that you reported it here, but it also helps to report in-game so that the devs get all the data)
I tried to ‘F10’ it but that was non-functional as it would not save the report.
