lines in map

I was playing DA beta 1.6 build 6 and the map of the galaxy zoom level 3 kept showing lines displaced about 1 1/3 map lines apart. these lines seemed to be localized in my space only or around my space with the lines within my space of the map looked like open space and then around my space the lines continued in my color where I didn't control and no one else did. Mind you this seemed to be a minor problem and I would post a picture but I don't know how.
