i belive those black lines (for me theyre a bunch of big black speckles in lines) have to do with godrays. theyve been there since at least 0.8 although for some reason it wasnt happening on my original 0.8 save, but then when 0.8.1 or 2 came along and i started another save then it started occuring (and has been since). also only seems to happen during sunrise/set? or ive just started tuning it out

I'm not sure this is the same thing. These lines are visible at all times of day, they seem to be only based on physical position. I loaded up my game to double-check just now, it's 22:04 in-game and they're still visible. One of them you should be able to see by looking at the main window while going up and down the short stairs in front of the base entrance, with a good view of it if you stop around where the bottom stair meets the ground. It looks like some sort of weird reflection artifact.
