I agree the adventures shouldn't be given as daily quests. Takes away the 'daily' aspect of you have to do a 3 day quest after waiting several days for your explorer to find teh right one if you don't have it. And yes you can cancel them, but again, for me that's not the point of a 'daily' quest. It's something that you should be able to do in a day. It would mean more work I know but maybe some adventures which are specially for the daily quests which could be done in a day?
