Ughh this is infuriating.
I made a station core and got it to orbit, put an arm up in a second launch. Went to intercept them, and when I try to plot a maneuver in map mode, it makes the node, but when I adjust anything, pro, retro, radial etc etc...... it slides, and tells me how much dV for the burn, but doesn't draw a new orbit.
So I ran the training wondering if it was locked or something. Nope. still didn't work. So I started a new save and base a basic rocket. put it up and i could map maneuvers just fine.
So I thought, ok, just some glitch, so I deleted the old save and kept playing on the one that worked... and I tried it a few more times, no issues. Then I decided to re-make my station core and put it in orbit. And god damn it.... I went to the map not expecting any issue, and damn it. It doesn't work anymore.
IS it possible its the higher part count ship breaking everything? When I tried making a simple ship again to test, it works, but when I switch to the larger station from the small ship, it no longer works..... Anyone else have this issue?
