I make an insert from the drawing. I have more than 300 such inserts
Sometimes a part of a curved rail is not inserted by the drone, the drone holds it, but does not insert it. I have to insert with my hands.
This manifests itself completely by accident, buoys twice in a row, it happens 50 times that everything is fine.
I do not understand what it depends on, everything seems to be as always. The last three times I took screenshots



Oh yes, the insert is done between existing railway tracks
