After defeating Draconis outside and entering the lair, I can't proceed any further. I am supoosed to pick up the bottle of empty breath and with that I should be able to explore at least two of the 5 (?) diving wells. However, I can not. I can enter the first well, proceed to the Salamanders and the Fiend room, return to the main cave, but when I try to enter the next well on the right side, nothing happens. I constantly get the message that I can't hold my breath for as long as I need to.
I tried getting me another bottle, using the console, as well as leaving the area. Nothing works. I can't continue.
