I have a problem. On the quest "Critical Discharge", I kill all the golems, and Melvin tells me "excellent! Now we should look inside."

He then proceeds to the locked door. And nothing happens, he just stands there. If I talk to him, he gives me the same line again.
Eventually O got tired of waiting, and opened the door via console. He walks in immediately, but nothing happens inside either, he just gives me the "Excellent!" line again.

Is this supposed to happen?

Normally, not. It MAY happen if you use autosave too often (this thing is buggy). Best if you upload your savegame.

Damn, nevermind, my computer blue-screened yesterday... I had to install windows again, and download Nehrim...lame.
But thanks for a quick reply!
