Basecamp started vectoring bypassing mapped roads?

SInce the latest update of Basecamp ( 4.4.2 a few days ago) , when reviewing a route I have created, I have noticed that the Basecamp is sometimes vectoring or tracking portions of the route and bypassing small sections of the mapped road.
In essence it is showing a route where there is no road. Will directions still be provided correctly by the Nuvi after upload? This is a bit concerning since I will be on a 1000 miles ride. Any insight? I would like to provide a .gpg only 62kb but the website wont upload the file.
