Sometimes PCs get stuck on scenery after being placed in “Hide Mode.” I’ve shared a video to Twitter to highlight an instance of this. This can mean that they can’t be controlled unless you go into the main menu. Or moving a controlled PC away and “Re-Grouping” if they’re out of “Hide.”
Also the spot that they actually end up standing in can be glitched by a square or so. Again photo shared to Twitter.
Not game breaking but worrying and an issue on Ironman.
