World Map bug

Map nodes connecting strangely.

See images below:

First completed map at mouse.: https://i.imgur.com/oe3c8Px.png
Then moved to complete this map just below it hidden by mountain: https://i.imgur.com/nXPrNj2.png

The adjacent tower wasn't completable however, I could access the map way below it and not connected to any other completed node: https://i.imgur.com/BOE3Azm.jpeg
