Notice the rescind was processed before the offer was given. This means the
offer is in the offer storage, but using it is invalid. It will cause whatever
task launched with it to fail with {{Task launched with invalid offers: Offer
81e04cbd-9bce-41cf-bd94-38c911f255e4-O142359552 is no longer valid}}
