I have clocked up 90hrs+ with my character completed all the main quests and othr quests etc this is the only quest i need to do to get 100% Please fix it many thanks

Problem: After competing in a drinking contest with Sam I don't black out.

thanks

If you received notification that ysolda is dead, you cannot complete the quest.

Not received any notification of that :/ unless it is one of the quests, main theives or any other faction then i havent killed ysolda

I did same quest earlier today and had same problem - it finally worked when I hit start button(was gonna check quest update)

Be careful though once further in quest - luckily I had previous save
But if teleport ball in dungeon does not appear( one that teleports you to misty grove) then reload at dungeon start until it does appear
Otherwise, you will get teleported to grove and get stuck there(Sanquine does not appear when Sam changes into him)- I had to reload twice and it finally worked

Tried pressing start a few times and it hasnt worked lol, i played for an hour or so after so would have been pressing start quite a bit to check stats etc thanks though will hopefully sort itself out like yours if i play more :/
