I did the same thing, but it was a no go for me.
My theory for this strange alchemy bug is that it was caused by the way I cold bloodedly dealt with that eminent Thay mage Vese Nejj whom according to Riki, I had to 'get permission' from to use the facilities.
I blue square attacked Dracein, knowing full well that if I didn't dispose her with a tactical advantage then, I'd probably have to deal with her later at a disadvantage. This causes Vese Nejj and his cronies to attack as well. Their deaths meant I don't get any xp for the Wizard Tower puzzle quest, but oh well - its all role-playing. [img]smile.gif[/img]
I'm going to take a stroll through the office tower tonight. [img]smile.gif[/img]
