When adding some feeds instead of adding the original feed (maybe NB cannot get them at the moment), the whole subscription gets reset into some arabic-like site with the address at “thendral.blogspot.com” and feed address gets generic.
I experienced that (with premium account) in the past while importing feeds from OPML file but I managed to add manually those that got reset. However the same happens now as well when adding feeds manually.
Is there a bug? It’s always the same site so I believe it’s not coincidence.
