Map chaining is broken

Basically you complete the node and next chained node wont be accessible..

+1 made my way to a few towers and alrdy both of them are bricked and unaccessible when i see there's a path.

Actually i just loook at my atlas and there's many towers that are just bricked...there seem to be a path but there's actualy not the towers don't evn have a "node". Very annoying issue :/
