Quest bug between different Characters

[Sheathe]

It might be just me, but I found that if you're on character 1 and you have clicked on a quest e.g dead at the top, (staying on the quest screen ) then swap to character 2 which doesn't have dead at the top activated as a quest it allows you to activate that quest without having to wait the period of time that you can reset the quest. It only works on quests that are available at your level.
