I have a single resistor with two wires attached. I give each wire a net label and add a NC to one of them. Now the ERC shows a warning that the NC is incorrectly placed (NET_B) but no warning or error whatsoever regarding the unconnected net (NET_A). I can parly understand the warning, although I like to name even the unconnected nets in the schematic and afterwards explicitly add a NC to show that they are not in use. The second point though is a serious bug in my opinion since connecting pin to a wire with a net label does not imply that it is connected to anywhere else. Any thoughts on that?

And I also agree. As long as a “No Connection” flag is connected to a net with only one pin, it is still an open connection and it should not give a warning.
A “No Connection Flag” that is not connected to anything does get flagged, and this is good.
A wire with a label and two “No Connection Flags” does not get flagged (which seems OK for me, although probably not useful.
Ah, thanks, didn’t find the corresponding issue in the tracker. And as Silvia Else wrote in the comments in v5 there was already a warning. But I do think it’s a rather relevant bug since the electrical rule check should check for plausibility and for example a resistor which is only connected on one side is something it should warn you about. No matter if the unconnected side has a net label or not, it’s electrically wrong imho.
