Messed up article count / no articles after access loss

[schaueho]

Some days ago, I had to reboot my XA2, after which Fuoten apparently had lost the account data. I.e., I had to specify all the details to access my Nextcloud installation. After I've done this, Fuoten synced feeds and articles but for some feeds, I don't get any articles at all when navigating to the feed via the folder structure.

The interesting thing is that actually new articles got synced -- I can see them in the "unread articles" catch all view. Now, I just read one of these articles and suddenly the folder view shows a super large number 4294967191 of unread articles for the feed, but when I select the feed I just don't see any articles at all.

I guess the database has wrong data and I should probably reinstall and delete the DB manually, but this is clearly buggy behavior.
