Huh, I've been using Adobe cloud (Photoshop, Illustrator, Indesign, and acrobat are the main ones I use) for my college work from a subscription and I haven't had that problem. I really can't think of any reason for the problem beyond something went weird with the downloading. If the problem started after you saved it, it may be something to do with the photoshop connecting to the cloud, but that usually only happens if you specify that you want it to do that...

So nope, sorry. No idea. Definitely the wrong person to ask, since beyond using it I have no knowledge of photoshop software. I'd definitely report it to adobe though since it sounds like kind of a big issue.
