Thank you Xoph. But i actually find a decent solution!

Asked around, finally got a response from someone who did the quests years ago. You can have all 3 Active at the same time. You're just SOL for 1 RL Day if you hit the wrong one.

Either way, Theres luckily a Way Around it, Still would be nice to have a Cancel button x.x; Or some confirmation before selecting :X

Just gotta pay more attention it seems !
