A question came up in the House Always Wins scenario last night. Jenny Barnes was in the party, and drew her weakness, Searching for Izzie, while we were still in Agenda 1. So we attached that weakness to the location furthest from any of us, which was La Bella Luna. So far so good. We'd already played Extracurricular Activities, so when the agenda ticked over we wound up going all the way to agenda 3. As part of that (agenda 2b specifically in case people need to check things) the La Bella Luna location was destroyed. The instructions tell us to "Move all investigators and unengaged enemies from La Bella Luna to the Clover Club Lounge." Searching for Izzie was still in play, but it's neither an investigator nor an unengaged enemy, so what happens to it?

We thought it should be destroyed along with the location, but had enough doubt that we went with the Dark Rule - pick the option that's worse for the investigators, and moved it to the Lounge. Anyway, figured I'd check in here and see if anyone had other ideas or better rules references to help out with that in case something similar comes up in the future. Thanks for any help.

You are correct, it would be discarded. It's in the RR under "Attach":

• Once in play, an attachment remains attached until either the attachment or the game element to which it is attached leaves play (in which case the attachment is discarded), or unless a card ability explicitly detaches the card.
