Warning to Ironman players (I am not on ironman at the moment).
Just had a bug where I was dashing forwards to cover. Path was behind two closed subway doors. My soldier ran into them as they opened slowly. It kept on with the running animation into the door while it sort of glitched open very choppily (not FPS, just the animation). It suddenly opened and the soldier gained all momentum and shot across the map. It aggroed every pod on the way, far beyond my sight. It moved around 3-4 turns worth of full dash. Not just a visual glitch, the soldier moved physically there, but the spot I originally intended the solder to go to was also blocked now (couldn't move another soldier there), but empty since my soldier was half way across the map. Turn ended and it got mind controlled far the hell away and I lost sight of it as the map then closed since it was far away from any visual range.
So yeah. That's a thing that can happen.
