In my MyTeam career mode, before each weekend I am prompted to select a Tyre Allocation from "Softer", "Balanced" or "Harder".
For my Monaco GP weekend, I selected the "Harder" allocation as I wanted 2 hard tyres for the Race. However I have since gone to the race weekend and I have been given the "Balanced" allocation which gives me 1x Hard Tyres and 2x Medium Tyres for the race.
I am not sure if this is a bug or intentional so am hoping for some clarification.
I have attached an image of the allocation given to me for the Monaco GP I previously mentioned, as you can see it is the "Balanced" allocation rather than the "Harder" allocation. The circled Medium tyre set should be available to me in Practice and the Hard Tyre set allocated for Practice should have been allocated where the purple circled tyre set is; if that makes sense.
