I read the original post here viewtopic.php?f=16&t=85&p=579&hilit=bitter#p579 and unfortunately there is another bug related to this quest.\
- I can start the quest
- Quest item well added to my bag
- Quest well noticed in the quest log (previously fixed)
- Questgiver has no more the exclamation mark (previously fixed)
-- BUT --
- In the Thunderbrew distillery at Kharanos you can't speak to Jarven, but you can click on the barrel behind him
- Clicking on the barrel will make a question mark appear above Jarven head - you can now speak to him and buy him a beer for distracting him from the barrel
- Buy a beer and give it to Jarven, he'll go upstairs
- Clicking on the barrel won't work anymore = stuck
