Drivers didn't pit

I don't know if this is considered a bug or not, but something's wrong. I was on course for a 1-2 finish, and on the 18th lap, but drivers (both of them) decided it was a wise move not to pit, despite not being able to finish another lap with the fuel they had.

^ That's the race that it happened on. I should have called them in manually, but it's never happened before that drivers do not pit when they will run out of fuel, so I don't know why it was different this time, and by the time I had checked, it was too late.

It was for me. :D

I had an opposite problem two races ago (and you possibly remember Jamie, since we  talked at the time). My drivers decided to pit with two laps ahead, for no reason (2 laps worh of fuel, no weather change, tires in reasonably condition). Fortunately I was able to cancel manually the pit calls, but sometimes it can destroy your races. I would admit that something went wrong inside driver's head, but on both of them on the same time ? I think it's a bug.

It happened to me on the last race of the season where I needed a 1-2 to have a chance at winning the constructors championship. I cancelled my pit stop because the driver had 1 more lap worth of tuel. Usually the drivers pits on the next lap, but this time he didn't and by the time I realized it he ran out of fuel,
Race ID: 8413
Let's hope we will have an explanation on this one.

Both happened to my son already. Pitting without need and not pitting and getting out of fuel...

Yeah, I do remember that Alin, it was at Brazil, if I remember correctly, and one of my drivers wanted to pit in that race for no reason, with lots of fuel too.

Clearly, this is an issue that needs addressing, especially as it has caused two people (if not more) to lose a 1-2 finish.

Jamie, I understand you're upset, but if I may a joke: your drivers are not able to finish a race properly. Either they pit when there is no need to, or don't pit at all and run out of fuel. :)

I've fixed a problem with the pit stop cancel order.  In certain situations if you cancelled a pit stop, your order would apply from that point onwards instead of just for the following pit stop opportunity.  This probably explains most of the problems people have been having with their drivers failing to pit for fuel or tyres.  Please reply to this thread if you notice this happening again.  Thanks.
