[V17.51 - Ground Combat] - invisible civilian (?)

On my second mission, Farm map, I encounter a shadow moving - no figure was shown and no enemy in sight. Tried to take a screenshot, but got only desktop this time too... I tried to use SnagIt to capture screen, but this also only grabbed desktop....

I had a couple of invisible civilians on a farm mission today, including one that was up against a hedge so I couldn't even see the shadow. I started throwing grenades at that spot and I was finally able to find him when he became suppressed.

I saw this in 17.1, it shows up and goes away...never seems to hurt anything, just a visual glitch

There are some invisible civies, we are on it .

Non combat Caesans are also shadows in my games. The very first aliens you get in downed UFOs.

They die with a normal animation though.
