Is this a bit fake? Perhaps we should just restart from the latest persisted state, but that also means that payment tracking may be off a bit.

Yea, I mean this is kinda emulating the behavior we had before where we persist on every iteration, except now we only make sure we persist every time before we read it...Indeed, we'd have to handle the payment tracking parts, though :/.
