I’ll end up relaunching the latest module for my surface base which I got all the way to Ganymede, then found that a separator was interfering with the docking ports. Since the 1.5 separators look like their hit boxes will stay within the space that they take up, the problem will sort itself out. Of course, I could just as easily replace it with a 6 wide separator and an RCS, but... procrastination, yay!
