Do expeditions have an expiration date?

I've got several expeditions for fruits backed up after spending a day away from where I live. Will these eventually expire or is it possible to eventually complete all of them? If they don't expire, is there a maximum number to queue or will new ones always pop up?


Solution 1:

They definitely expire, after a couple (~5) days. Noticed it for myself, but also mentioned in this beginner guide from a Reddit beta tester.
