I have the flaw DF154 and DF119. After deleting the flaws, everything is OK again and again, but at times it starts again. Not always, but sometimes the flaws are saved again, but in variations. Sometimes only the one or only the other – or both. The whole thing preferably in rainy, cool weather. What do you think? The classic? OT-gover over or oxidizes cable? Just change on suspicion?
