Probably due to this. https://github.com/patsonluk/airline/blob/master/airline-data/src/main/scala/com/patson/AirlineSimulation.scala#L535

If shutdown occurs after this but before cycle ticks, next sim will likely catch up again but we dun want to re-deduct the money. hmm it's more of a problem of handling of shutdown during sim
