CC Library breaking my assets

Hi, myself and a colleague are both having an issue with the syncing on the library lately. I was working on a cloud asset and after some time from saving/updating i closed the file and the last update to the asset didn't take. When i try to re-open or edit the file does nothing - it WILL NOT launch the file again. After restarting PS the asset is de-linked and i can't get it back. All copies of it are stored through the library so now this file which had alot of layer comps and assets is completely gone - this happened to two others i worked on as well!

I even tried to check my local temp file for the psb which gets geenrated there and it was a png image and no other file, its wrecked. it shows broken in the library list like in the image.

I am now considering keeping de-linked versions of everything in files as well to restore them, which totally defeats the purpose of having a library like this really.
