Hello ,
First of all, apologies for the inconvenience and thanks for your time.
It's my mistake :P . There should be a preselected race when the user enters the training menu. Otherwise, the user must select a race before clicking on the start button (or else this error occurs). It will be fixed in the next version this week.
In the meantime, if you feel like playing in training mode:
- First, select an unlocked race.
-After click start button if you want to drive or show button if you want just to watch a race"
Thank you very much for finding such a big bug.
I hope we will talk again.
