Unable to buy Better Crowned Pie from Talan?

Anyone else been unable to buy Better Crowned Pies from Talan recently?

I don't have any of these pies in my nor my retainers' inventories, and yet every time I try to trade in for a pie, I get the following error message:

"Unable to complete transaction. You cannot carry more than one of this untradable item."

Doesn't seem to matter which materials I'm trading in for the pie either.

I'm wondering if there's something I'm missing, or if this is a bug to report.

Sounds like a reportable bug to me.

This happened to me on the splendors vendor a few days ago.

It's a common bug, just leave a bug report and wait a bit, also try re-logging because that fixed it for me.
