First, the route is still there in the side panel under Star Routing, but I was no longer seeing the actual route visibly in the 3D area... until I clicked off showing labels, then it came back. Turning labels back on did not remove it again, I think it's just a matter of forcing a redraw of the 3D area.

Next, after the route was in place, I went to General and clicked "Plot Routes", which is where the error happened.

First, the route is still there in the side panel under Star Routing, but I was no longer seeing the actual route visibly in the 3D area... until I clicked off showing labels, then it came back. Turning labels back on did not remove it again, I think it's just a matter of forcing a redraw of the 3D area. (Route is Delta Pavonis > Sigma Draconis > Groombridge 1618 if that matters, but I suspect it wouldn't.) So the route is there. Next, after the route was in place, I went to General and clicked "Plot Routes", which is where the error happened. I've included the Exception info from the terminal; it mentions "... 53 more" at the end, but when I check the log folder the error isn't listed there. Also included is the best guess of where I started the route - there's a couple of clicks registered prior to that but they were looking at system information (aka "trying to figure out what I was doing"). That's in the attached text file. Do let me know if you want this written up as an issue on GitHub and I'll do that.
