Sometime after reacquiring the Sister's dragon, I've found I can no longer use the Forge of Daith button when it is active. It will light up and shine, but clicking it does nothing. I have disabling mods and it still has the same problem. The items I had previously acquired and upgraded are still there, and I can get new items from the Forge, but upgrading them is impossible. I have attached my save and the modified .log file.
Reproduction steps: Win a battle with Naestra/Arahan and be sad Forge Santa doesn't give presents
