That kind of thing happens all the time, but it’s another data mismatch that should have been picked up in end 2 end testing.
In the real world, for financial transactions, companies get their feet held to the fire overt the 5 day statutory limit.

To quote the famous American Politician
This would be, a “ big fu@@ing deal”
