Well... I was getting aggravated with it all, trying to figure out what it was about the US_NavalBases.mis file that is causing this issue (I suspect the file because I did quite a bit of editing in it). So I was going to give Jeff a "photo montage" of what it is supposed to (should) do, and what it actually does. When I just now disabled the US_NavalBases.mis file, it is still messing up, and the sun going back to 1300 elevation, but the clock says it should be sunset... So I'll take a couple steps further back, get some sleep tonight, and try again sometime tomorrow... maybe
