DRC does not report misconnected line
I will attach 3 screenshots, focusing on the connection of one last net on my PCB.
example1.png: Shows the remaining single rats-nest-line. DRC reports no errors. (Does it not report incomplete nets?)
example2.png: I have added a top-side line, but one end is too close to another pin (without overlapping). DRC reports an error, correctly.
example3.png. I have moved the endpoint of the line. Instead of being near the wrong pin, it is connected all the way onto the wrong pin. Totally wrong wiring. DRC reports no errors! This is the problem.
