Land units appear to attack from sea

[tegilbor]

I've had this really weird bug that appeared when I tried to attack a city that was adjacent to the sea with a land unit that was also stationed on a tile next to the coast: The game zoomed into the combat animation, but the land unit (a mech infantry) appeared to be gone. Instead, the attack seemed to come from the sea (i.e. I could see the gunfire coming from the sea instead of the land tile). I've had this kind of thing appear in various strange variations. I'll try posting a screenshot if this ever appears again.
