I noticed this while playing FMP 1.5b...
Crashed Sentry ship, Floater race, Officer-887 "Lioness" and her two rookies in training (I prefer codenames for my soldiers, they sound cooler than regular names, and the numbers are there to uniquely identify them) are out grenade-spamming the hell out of them (because they're all grenadiers, even Officer Lioness), and the Floater shoots a Heavy Plasma which whiffs over Lioness' head and hits the door of the Skymarshall.
AND THEN SAID DOOR IS DESTROYED. I SHIT YOU NOT.
Was that supposed to happen?
If you don't trust me, I have a savegame. If you try to get Lioness or one of her Rookies to go into the Skymarshall, you will notice a severe lack of left door.
