Do this as an experiment, see if you will notice this issue.
Take a PCB design that has lots of resistors, and in the schematic, change all the resistor numbers. Then update the PCB. You will see a net error for every one of them, of course, because the net name no longer matches the part. I fix this by changing the name of the net in its attribute menu. But,you will also get 1 or 2 net errors that don't make sense. The only way to fix is to delete the net and rewire it.
Brand new interactions and interfaces. 
Easy to use and quick to get started.
