Look, I made a complete video creating a career from scratch with 50% race to show you the error that the last tire does not appear in the feature race (in the video the game is all in Brazilian Portuguese because I am from Brazil) if you want to watch it are you there. I will explain correctly in the text below.
I'm already in the full Qualy, (I added training but it's not necessary to do it just for this explanation) I did the whole Qualy, two laps with the first soft tire. then I go full sprint race with zero stops with the standard hard tire strategy. I went to the Race feature. this is where the error happens, in the Race feature strategy you can see that he asks for two stops, start with the new soft tire and at the first stop put the used soft in Qualy and the second stop put the hard on the last lap, and this Hard is the one used in Sprint. (you can be sure seeing that already on the second lap of the feature race I put the tire on to check if it is the hard sprint and you can see that it is the sprint tire, due to the wear that is the same when we finish the sprint race ) and I'm left wondering where the last new hard tire is. why doesn't he show up. that is the problem. the right thing is to make a stop, for example use the new soft tire until the 7th lap and use the new hard tire that does not appear until the end of the race, just like in real life.
unfortunately here you can not post the video so the link
