Finally got around to cracking this game open (after owning it since early May!) and was working through the intro quest solo. My apologies if these questions have been asked and answered...this forum doesn't exactly make it easy to search for specific answers to specific questions!
1. Do duplicate copies of Locations remain in the staging area? I wound up in a situation where I had duplicate copies of a few different locations in my staging area and it wound up being impossible to make any progress on the quest.
2. Can Snowbourn Scout add a progress token to locations in the staging area?
