I am trying to rename an instance to, for example, K0, but I get an error (SCH-1025): Instance name "K0" is not unique. I am sure that there are no other instances currently named K0 in the schematic.
Is this a bug?
I think this is a cache problem. Is there a way I can clear the cache of instance names?
You didn't say the version you're using - of course the oaScan approach won't help if it is IC5141.
