Possible bug?

[Grumbler]

Narwan, in a clearing in dense woods, level zero, with several tree hexes between them and any elevatons, which were beyond Vis range anyway. I'm 99% sure they are radar guided 57mm AA guns. Radar guided missiles can and should be able to shoot around (over?) hills and LOS obstacles, but not guns. I wonder if the guns are using the to-hit algorythm for missiles. That would explain it. It's no biggie, it just seems inconsistent. I am also a little worried that because I didn't drop off any passengers after landing, the program might have raised the helios back up to low level. That does concern me, since I land my helios a lot to avoid Flak.
I have saved both sides of the turn.
