Grymforge won't cast a second item

[ShOAB-0,5]

After killing Grym, I can place another mold and an ore, but the lava valve won't budge and no item will be produced when working the hammer. If ride the elevator up, the forge becomes unusable altogether and can't be interacted whatsoever, even after lowering the platform again. What am I missing?

Update: So the order of actions is actually important. It worked for me without going to camp, but before taking out the first item, I needed to raise the platform first.

Try reloading and then first raise the platform after killing the boss and taking your first item.

The trick that worked for me is going to camp and returning (don’t long rest). You’ll also want to do what the last comment said and raise the platform before trying this.

I was able to cast my second without raising the platform. Just pulled out the item, dropped in the mold and mithral, ran lava and stamped it.

Right, that’s how it’s supposed to work. OP needs a solution to work around the bug.

I appreciate the answers. If this really is a bug, that's kind of hilarious/dissapointing considering the length of this whole sidequest. I will report if any of the solutions worked for me.
