Quick question. I understand that unconnected nodes need to be corrected, but I'm unclear on whether nodes connected to a single routing path are an issue or not? A node at the end of a single routing path, not connected to anything else, I mean.
They are only a small issue but if possible try to avoid them (especially in areas with more "traffic"). Sims sometimes are too stupid to turn around and go back, also the path can easily be blocked by another sim (stray dogs etc.). Horses very likely will get stuck on those, too
