**BUG** Concise problem statement: On a nearly completed PCB, the ratlines for an entire net (Vcc) appeared at some point. A careful inspection does not reveal any real connection problem. Steps to reproduce bug: 1. Hard to reproduce. Make some edits to PCB, eventually they may cause nets to appear unrouted. 2. Closing the PCB and re-opening solved the problem. 3. Exporting as source and then creating a new file solved it as well. If desired, I can provide the source file, but it won't reproduce the problem. Results: Routed net shows as completed unrouted, not just a few connections. Expected results: Routed net connections should not show ratlines when still connected. A workaround was to close the file and reopen it. A refresh button would be useful in this case if the bug is too difficult to fix. Browser: Vivaldi
