Dropbox + Cubase

Hi all,
I’m having this same issue with Nuendo 10 and Dropbox client app. I noticed that if I create a self contained project on a different drive and then drag it over to the Dropbox folder, when I go to open that project, it comes up with missing files. The weird thing is that I can’t easily find those missing files either-- I’ll point to the folder which clearly has the files in it, but Nuendo still doesn’t resolve the same way it does on a regular work drive. Feels like a bug or something else going on with DB. I’m going to try creating a Nuendo project in the DB folder first and see if I get the same result. Also going to test if I drag it out of the DB folder to a different work drive, will it open normally. A little unnerving.
