Hi, I created a PCB and ran autorouter without a problem. After adding a new design rule, autorouter does not route anymore, staying on 0% and program keeps saying 'routing'. This happens both on the local and remote router. Deleting the design rule does not fix the problem, so I am left with a PCB without routed tracks. I have to delete the PCB and convert the scheme back to a new PCB, having to place all the components back on the PCB. I did it on a smaller scheme and there I could not reproduce this error.
