What did you try to do?
During changeable conditions, multiple cars qualified on Softs.

What happened instead?
Due to the drying race logic, many cars subsequently started the race on Mediums. As this is a 2 tyre league, this caused half the grid to DSQ. Sadly this ruined what was shaping up to be an exciting championship battle.
Tyres can rightly be changed between dry <-> wet on the grid to account for changeable conditions. But I am not sure why/how compounds can be changed prior to the race.

Did the problem happen while using wi-fi, mobile data, or both?
Both

Did the bug happen in the app, on PC, or both?
PC

What operating system is your PC?
Windows

Which browser did you experience the problem in?
Firefox

Can the bug be reproduced?
Not easily, it depends on specific weather conditions (dry pre-cut-off, wet in the 10 mins before the race, dry at race start)

Additional comments:
I know this has been reported many times, but it would be good to have this fixed.

First of all I agree the logic is flawed and AS is about as much use as a chocolate teapot for offline racing. You can use it to qualify on the right compound but during the race it's a lottery, especially in changeable weather conditions.

For your race at Silverstone the qualifying page shows all cars as qualifying on slicks (either SS, S or M Great Britain Qualifying

But if I look at all the individual race data sheets it shows many of the cars starting on Inters, doing one lap and then pitting for slicks. Even some of the cars that weren't DSQ are shown as starting on Inters but they ran a second dry compound later in the race.

I accept it's wrong but out of interest, what was the AS for the cars that are reported as starting on Inters? Was it different to those that started on a dry compound?

Hi MD

I'll try explain exactly what happened and why in your race. One of our volunteers happened to be racing at GB19 at this time so we have decent feedback on how the weather played out.

Rain started at 22:51, this triggered advanced strategy on the grid to fit inters for those that had it set to fit I if water greater than 0.0mm.

The rain stopped at 22:56. This would/should have triggered the second advanced strategy of anybody who had it set to 0 laps to kick in. (I'm not 100% sure what happens on the grid if it is not 0 laps). i assume most people had either 0 I, or a number of laps and a dry tyre compound.


between 30 and 0 seconds before the race started, the track fully dried out. This is significant as tyres cannot be changed on the grid in the last 30 seconds. So the inters (or other as dictated by advanced strategy settings) on everybody's cars remained fitted. If it had dried earlier, cars would have gone back to the original compounds.

The race started as a dry race, and therefore the two tyre rule of: all cars must use two different dry tyre compounds was active.

Nearly All cars on inters then pitted on lap 1 for the tyre allocated for the second stint.

Unfortunately as Kevin highlights, most of you had the softer compound first stint only, and therefore got disqualified.

So it really was a bit of a perfect storm in terms of everything that could go wrong did go wrong.

Thanks for the reply Kevin.
Good question, I am unsure of the AS of the other cars that started on inters. I suspect similar to mine (fit inters with >0mm) rain.

I think there are several options for an "easy" logic fix for this. This can either be in the AS itself, or even in the logic of tyre compound counts for the race e.g. include the qualifying lap tyre. Of course, there would have to be confidence any logic changes don't open up avenues for cheating. 
Another option is to relax the 2 tyre criteria to say any two tyres, rather than dry. Realistically this covers both dodgy weather and also minimises cheating options (inters on a dry track would be rather slow!)

I'm ignorant of the number of online players vs offline, but in a game of such fine margins I think investing in a fix is worth it :).

Hey Michael, just saw your reply as I hit send on my reply to Kevin.

Much appreciated on the timeline. In terms of my AS, the other thing I set was for Mediums to kick in after 3 drying laps. It's one of the main reasons I was confused about the pitstop on lap zero. regardless, even if pitting on lap 3/4 I still would have been DSQ'd I guess.

With tyres set to mediums after 3 laps, I suspect that you would stay on inters on the grid as no laps have been run to trigger that change.

The second section of advanced strategy means:

When rain has stopped, wait x laps and then fit selected tyre compound, use this compound until the track is dry

Since the track was dry on your first lap, I think this would explain why you pitted immediately instead of after 3 laps. The system was reverting you back to your original strategy at the earliest opportunity.
