I fixed the TPF error, adjusted the TPF-INT connection to be more visually pleasing to me, removed R&R from XX and connected it to FARK & MHA. I'm displeased about how I have the treaties running right through the XX circle, but it was either that, long looping lines which are hard to follow, or another major overhaul. As it is a beautiful day here, I'm not willing to commit the time to the last option at present, but it's probably coming soon: rotating the South Pole so that Sentinel is on the very bottom would greatly shorten the north-south lines. Also, with R&R departed from XX, I can spread things out a little more down there and hopefully replace some of the awful curves with straight lines.
Coming soon: GO and maybe CoJ, but at this point it's really more fun to tweak them through exclusion.
