I'm not sure this is actually a bug. Every time I get the map "Fuel Dump" I start outside of a compound, with my units deployed in the woods. The enemies all spawn inside the compound, with no apparent route between the outside and the inside. Twice now I've killed every alien who poked his head out of the upstairs window, and been stymied by a unit somewhere inside who never comes out. I've gone around the entire compound clicking for a way in, but nothing is obvious. Is there some way to make my soldiers open the front gate? Is the strange sparkling cloud of gas some method of teleportation?
The map has loaded identically each time, so I assume its not loading incorrectly.
With that small nitpick, thanks for many hours of a great game. Your hard work is appreciated
