I just ran into this and did this sequence to get it to work - your results may vary:
- Put new mold in
- put ore in (get error), put ore in crucible again
- hit with the hammer
- open the lava gates (this time it wasn't stuck)
- hit with the hammer again
got my second item.
I don’t think this is intended. I managed to make two adamantine items, though I didn’t have two lumps of ore on me during the golem fight, so from memory my sequence after it was (1) retrieve my adamantine armour, (2) raise the platform, (3) collect another lump of ore, (4) eject the old mould, (5) insert a new one, (6) insert new lump of ore, (7) use the hammer lever to go back to the lower level, (8) open the lava flow, (9) use the hammer lever to make my new item.
But if you have a second lump of ore, I don’t see why you’d need to go up and down again. As long as you have new ore in the crucible and a mould in the appropriate place, and the platform is at the bottom, I’d have thought you’d be able to operate the lava flow.
If saving and reloading doesn’t help, then it sounds worth sending your savegame to Larian via their support website or the feedback form on the launcher so they can investigate.
Everyone, thank you for your responses and I appreciate the attempt to help, but I am reporting a possible bug. I understand how the forge works, I got one piece made, I have the items needed, I am saying that after the fight, the crucible is not able to be interacted with nor the place to put the molds. Prior to the fight, they could be clicked anywhere and the combination window opens up to place the item in. The only places that can be interacted with after the fight is the eject lever and the lava lever, which say they are stuck.
I will see about sending them info on the issue through the launcher, but I do not see how to upload a save file, would they ask for that? I thought that reporting here was a good place.
