Happened 12/31/2023, so recently. Not sure how it happened, but it seems to be an issue with the list collection screen in this interview where we get other_parties. Can't recreate it.

Since you weren't able to recreate this bug I'm tempted to close this issue, but since we're actively working on this interview maybe we'll see it again in our testing. If not, this comment will remind us we can close it.

It looks like the next step is to test thoroughly, either manually or by adding thorough automated tests.
