Missing Category Logo Image

We have a live site where we have Category Logo’s for each category. Yesterday we noticed that all our category images were just gone… We thought that was odd and we added them back… today some of them are gone again.
Files are physically removed.

I am wondering if the cleanup task is somehow picking these up as not used?

Off Topic and FAQ are missing… now

Is this the same issue?


Look similar and we did edit those categories yesterday to change the email settings!
