I also had the Problem with the first Race at Melbourne Season 2 .
At Practice and Qualify the Tire wear was extremly heavy after 6 -7 Laps on Hard Tyres they had only 60 - 65% left .
Before the Race i could not change the Strategy , because its greyed out and set to 0 stops .
The Race ( 100% , Legend ) was really crazy , no one from the KI stops , my soft Tyres dont live longer than 5-6 Laps . The KI slides , crashes and run off the Track all the Time , 2 Laps before the End the last KI Cars alive stopped to take the Hard Tyres .
I must stop 6 or 7 Times but won the Race by 4 or 5 Rounds ......
The rest of the Season it works normal .
Now i reached Season 3 Melbourne and same Problem with Tire wear and Strategy .
I drive on Pole with an 1:22,8 , but no chance to change the Strategy of 0 stops before Race .
Then i tested an Idea wich i had :
I switched from 100% Database to the Original and Start the Game again , and what will i say ? The Strategy works with the Original and was set to 4 Stops , also i could make Changes to it , all seem normal !
After that i startet the Race to see if it works normal and yes it works fine !
KI stops normal , my soft Tyres are good for 10- 12 Laps , the Hard Tyres 18 - 20 Laps .
I make 4 Stops - soft , 2 Times Hard , soft an KI stops also 4 Times , most oft them soft and 3 Times Hard Tyres .
It works !!
You only have to Change the Database to the Original before you start the first Race and all works fine !
I think after the Race you can switch the Database to the modified and have no Problems for the rest of the Season but i not testest it yet ...
