I am trying to modify my Net Classes to be wider to run AC current through. (25mil). However, when I add a new class and then try to autoroute it doesn't use that new class. I get an error saying The autorouter job and current drawing are different and if you continue current drawing will be lost. Then an error saying that the Board and Schematic are not consistent. Additionally, it reverts the net classes back to the default net class settings, so the new class doesn't exist.
I have added the net class to the schematic, tried saving, saving and exiting the program, but I can't get the net class in the board to stick.
How can I get them to save?
