There are many, many minor issues with the Hills map. None that actually break the map, but things like entire rooms and balconies becoming impassable when a door is opened, soldiers walking through brick walls, rescue zone located under a harvester's wing instead of in the Firebird etc.
I need to put together a coherent post sometime tomorrow evening, because I need to do some screenshot doctoring to make a proper bug report and highlight all of the places where things act weirdly. However, in order to not accidentally delete the all-important console log of the map info, it is added here as a preliminary measure.

Oh, and props for whoever designed this map despite the issues. That was without doubt the most X-Files map ever, with no civilians anywhere, just empty houses, an alien right at the start and then just the great, looming harvester on a hill above the suburb at night. Never had a mission as tense as that one in terms of atmosphere.
