My local venture officer just posted on our Facebook page:
"Just for everyone's clarification, Pathfinder 2E scenarios, so far, are all repeatable, even though they do not have the repeatable tag. Paizo has a note on the reporting side that scenarios are repeatable."
This was along with a screencap of the reporting screen with the words "This scenario is replayable and will grant credit each time it is reported." But it was on a scenario without the repeatable tag (#1-12: The Burden of Envy).
I have a feeling this is incorrect and an error on the reporting page, but is there an official source to confirm this either way? I'd hate for players and GMs to go through adventures and not actually get credit for them.
