Has anyone ran into alt tags not saving? If I'm logged in via the cp, and go to assets, then click to edit an image I'm presented with the Title and Alt field. When I type in those fields and click save, it shows that the alt tag is saving, but when I reopen the edit image area, the fields are empty? Any ideas?

As a follow-up, I'm looking back at some alt tags I wrote a few hours ago and those are now showing up. Could there be a cache that also affects the visibility of the alt tags in the control panel?
