... how did you get the disjointed routes to begin with? i'm quite curious, so i can prevent future occurrences.
You cannot close any of the routes, because to close any single route would leave disjointed fragments therefor the code throws up warning flags. That's why it's saying there's a joining route that doesn't actually exist (the code is only so smart, and though it's smarter then last age, it seems there's still some gaps in logic).
I'll look into it from my end, but any further information you can shed would be lovely. and likely most helpful.
I've got to run at the present moment, but i should be able to close either two or all of the routes, if you so desire, within 24 hours.
