Sync is "up to date" yet many folders are missing from the backup folder

hey. i use dropbox for work syncing and file sharing, aka i have all work stuff on a synced dropbox folder.

this is a glitch that happens in very deep dropbox folders. i have lost pretty big files and folders plus i depend on a lot of linked content which sometimes just does not exist. this is why i now do a dumb backup of all files in my dropbox due to the servers sometimes either forgetting you had a file and just not syncing it to outright deleting files. this also seems to be a problem if you use non american letters like ÆØÅ that the dropbox servers sometimes just throw away. i have lost a lot of recorded audio due to them having unrecognizable symbols too. dropbox.. we rely on you, please be super vocal about this if it is a problem, we will get it but don't act like the problem doesn't exist. we would rather you be up front about this and let us use you in a limited manner rather than letting us lose stuff and then replying with "we are looking into the issue".
