OneDrive for Business sync

Hi everyone!

One of my clients have an issue with the sync in OneDrive for Business, sometimes when he uploads a file to OneDrive it gets moved to the trashbin after a while. We're not sure what causes this behaviour but I'm pretty sure it has something to do with him using multiple computers(cloned machines for developing). The might have the same SID and GUID, but I'm not 100% sure, is that a cause for error?

We've had many turns with the support about this so any help would be appriciated.
