Tracks I made with Pcbnew dissapear


Jun '18 - Some of the tracks I made just vanish after they are complete. I draw the tracks manually rather than use the autorouter. The disappearance happens when I move the board image or when I try to write another track. The rat nest lines are in place and the DRC rules point to a correct starting point for the trace. Most of the tracks I make are all right. Usually there are one or more vias between segments. This happens a lot, I am surprised that this issue hasn’t come up before.

could you post a screenshot that shows us one of the tracks that vanishes? (Maybe one before and after it disappeared)
