After opening old (~1 year ago) project in fresh EasyEDA I got nets error on 2 net ports (other net ports are OK). I tried to remove and re-add nets - it doesn't help; adding net description throws error "network label can't be placed on net containing No Connect flag" - but net has no No Conect flag. When I try to conect net ports by wire - all is OK; but when I remove wire - net errors appear again.
