I've been using this mod for a while and it's amaizing, aldo now I don't know if it's becouse of an update, but the cars appear invisible on career (In time trial I can see them), also i've notice that the Williams and Mercedes livery now has some little errors. I verified files and re-installed the mod again but got the same result, so a bit sad not being able to play it again.
Now it may be due to the performance of each car in the current season, keep in mind that some cars evolve less than others in the MYTEAM seasons.
Also, I'm glad you liked the mod.
