Josh Bishop, We don't have a research animation for the dwarf.

How did you break the final door is my main question, and if you restarted / loaded a save game is very important

Hello Steven, sorry to hear you also get the issue. We have hard time replicating the problem. Did your units killed the door next to the priestess ?
For now you can save and simply load. If the door is missing the level will end =)

There is nothing particular for Vampire in Crucible. A few more units than usual are able to kill them but apart from that nothing. Their respawn have nothing to do with the gateway limit =)

Ahah _ It was the last portal so Gandalf could spawn I fixed meanwhile that one could destroy a non attackable prop in possession. So you're maybe the last one who destroyed the most cherished portal of Gandalf

Just a small comment to remind that AureateMonolith turn even your units into Gold statue. Just sayin' because I ended up once wondering why I had so few units ^^

If you update your workshop item, subscribers will get the update. But if you test locally, you have to restart Steam ; )

Also, do you have a save file before attacking the Dwarf ? If so it would be perfect if you could upload it = )
