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is no longer valid}}
