Monsters From The Mist is blocked

One of the task during the "Monsters From The Mist" adventure was "Shut them out" (block road with a BarrierConstruction Kit buff) .
So, I did it.

Now I have to pass the last task - "Defeat the mad Scientist", but I cant get to his camp because the road is blocked by the "BarrierConstruction Kit" from the previous task.

It seems something is wrong with this quest.
Could you please advice. :(

you need to make and use 2 torches as well
before you get to mad scientist camp

if done that and its still broke then i guess sending ticket next option

hi, thank you for quick response.
it seem the problem was into IE Browser. I'v passed the quest from FireFox.

I had a similar problem - couldn't target the Laboratory. I reloaded the page on my web browser, restarting the game, and this solved it.
