F1 World: Increased difficulty with modifier affecting other events

I can also vouch for this issue. Increasing the Tech Difficulty seems to increase the difficulty of AI in the F2 events and the "Official F1 car events" and they become impossible to beat.

In one F2 race, the AI were within half a second of the current WR at the track.

Going into a my world car event and turning the tech modifier down again returns the AI to a beatable level.
