Artwork not changing - iTunes on a NAS?

[Risco]

I had to roll back to Mountain Lion as I was unable to update any of my movie or TV artwork. Every time I deleted the current artwork it would flicker, then instantly revert back. Same would happen if I tried to paste and replace via get info.

Anyone else having this issue? No issues on the local drive, only over the network.

This was happening for me, but randomly resolved on its own. Have you tried restarting everything? (iTunes, your Mac, then the NAS?)

I tried restarting everything. I clean installed and even formatted the NAS. In the end only rolling back to ML fixed it. At least it now seems like a bug!

Anyone else want to confirm this problem?
