After updating to this version the option of syncing deletions to the cloud was activated instead of unsync. Since I am on a dualboot system this leads to deletions of files I add with the windows native client when starting linux again. The update changed that option. I don’t think, this is an expected behavior.
EDIT: Why don’t you add an option here, that the files are just redownloaded. I think this would be better then unsyncing.
