How about this for bizarre bug of the week: the latest version of Adobe Creative Cloud deletes the first hidden directory in root directories on Macs.

That’s bad news for users of BackBlaze: the backup software stores a .bzvol folder in the top level of every drive it backs up, and uses these folders to store information about the drives. Adobe’s Creative Cloud app wipes away these directories, leaving BackBlaze’s users faced with “your drive is no longer backed up” errors.
