Subterranio adds some new surfaces underneath 3 of the vanilla planets, but Redrawn Space Connections seems to think they're actual planets and draws space connections to them - often times instead of to the actual planet. I'm not sure if that's something that would be best served by a compatibility patch from this mod, or if the Subterranio dev should be adding some kind of flag so other mods don't see the surfaces as planets... Thoughts?

It's probably a missing exclusion flag, if it doesn't expect to be run alongside the base Redrawn Space Connections mod, but I can fix it from my end if necessary.

Worth reporting to them as well, if they are still in active development. It would likely just be one line of code setting redrawn_connections_exclude to true.

Though I would assume that hidden surfaces aren't taken into consideration either, since there's no special code for the Maraxsis Trench, and that one works just fine with RSC, without having the exclusion flag set (it's just marked as hidden).

EDIT: Just looking through their github code, and unless I missed something, it seems that they forgot to set the hidden flag on their surfaces. Pretty sure they don't want them appearing on the starmap, assuming there's a non-space travel way to get to those surfaces?

Roger that. I'll report to the author - it's under pretty active development lately. Thanks!
