Hi I have seen cases of “goes away until power cycled”. I have not seen any cases of “goes away forever” other than the obvious ( = feed it an insane almanac that prevents if from ever locking up ). Even with that said, I have not seen an example ot that sort of thing living through a hard reset … ( which isn’t quite the same thing as a power cycle ).
