Teleporting unit bug?

[magic9mushroom]

I was just playing a Terror Site and one of my units suddenly found herself in a location I hadn't put her in. I know I hadn't put her there because her new location was OUTSIDE THE MAP (specifically, one tile north of the north edge of the map). Her east-west co-ordinates appeared unchanged.

 

She was wearing a Flying Suit, and remained able to move up and down, although there was an invisible wall blocking her from moving laterally or shooting aliens ("No Line of Fire!").

 

Anybody had this happen to them?

I didn't see this happen in EU ever, though it happened a bunch of times to me in TFTD (don't remember which map, it was either a Colony or Artefact Site). Not sure what causes it, perhaps the game isn't properly updating the x-y-z coordinates or it's an overflow.
