@Darthsausage44Wait, what last lap bug?
About the wet races, I still needed more testing for post v1.08, because I felt they were indeed extremely strong pre-patch (at least on some specific tracks that I've raced on wet condition, like Canada). Yet, post patch, on my last wet Monza race last night, they were very slow compare to their dry pace with the same difficulty settings.
But, yes, the difficulty settings does get quite whacky at times lol, especially after they've done so many car / ai related patches in such short amount of time.
