have been working on a route in surveyor for a few weeks now and im starting to notice some very jagged lines running in and through buildings and my track. if i undo certain assets they will go away or if i move them they go away. some will show up before i place them on the layout, they lines are in the preview screen along the right, no clue where they came from or why. tried changing performance setting, that was no help. anyone have any ideas?
