I tagged @JamesChevalier on Twitter about this a while ago, but I don’t think it’s the “zero nodes” issue as he suggested. It has been this way a few weeks now.
Per the attached, I completed Vancouver and Victoria some time ago, now they show as 99.xx% complete. When you view those cities and click “go” on the incomplete streets, it takes you off the coast of Africa. Also, the University Endowment Lands suddenly has almost no nodes. This makes it pretty hard to plan runs to grab nodes and it would be useful if cities I’ve completed remained at 100%.
