So the folder itself exists, but it just appears empty? Have you tried with another IMAP client? Have you checked if the files are actually still there in the maildir? You can check if this is a server problem or a client problem by running:

doveadm fetch -u user at domain uid mailbox project.missing.sub.folder all

If the output is empty, then Dovecot doesn't see any mails in there (check if there are any files in the maildir). If it outputs something, then the client's local cache is broken and you need to tell the client to do a resync.

Subscriptions won't matter. Deleting Dovecot's files may emulate the client's cache flush because it changes IMAP UIDVALIDITY.
