Yes, there is. You can check the Replay button on the character screen on the right. Most scenes can be replayed from there.Oh, but you're the second player I heard of that didn't find the explore button. Time to make it more obvious!
Once I understood the mission the button was obvious, maybe a change to the task to make it clear that you are looking for new locations?
Whatever is easier!
Great game, thanks for all the effort you are putting in!
