Yeah, it seems like it repeats what the previous day was as a baseline or until there is a different amount of hours billed.
So if you have a 100k insurance bill one day and don’t log in to fly, you will get charged that amount every day you don’t play the game. At least that’s what it did to me for the last 3 days.
I haven’t quite nailed the logic that it’s doing, but it’s not correct.
