Would definitely need some advance planning on handling the numbers. [Especially if they wanted somewhere for people to come back to if they ended up injured or tired, like with the last hunt the Heavens organised.]

I'd say that would've been a bad time, with how focused everyone was on cleaning it out. But with the crystal, not hearing word could mean either nobody's found it or someone has it and just doesn't want to tell anyone.

[Neither option being particularly promising, really, though Shun can somewhat understand the latter if it's one of the new gods or shinki.]
