List the bugs, I'll fix them.
Talking of a change/bug since the W2W update, the default set-ups now pull their stats from what was rookie after all the tiers were merged. So now the set up for every track is just between 1 and 10 on wing level, ride height and suspension. I don't know if this is intentional, but it would certainly add more depth if the set ups were pulled from the old elite range.
Additionally, as brought up in the open letter, the change to the transfer market refresh period is one that goes against the wishes of most managers and is rather an easy fix - though I am aware this is an intentional change rather than a bug.
Also, in terms of driver recovery time being different with age, if you train a driver at 10x right after a race, they need to recover at 4.55% an hour to be able to be at full health again for a race the following day. This means that not only do older drivers atrophy way faster, but they also can't be trained as much so it just worsens the effect. Realistically, the minimum recovery rate should be 4.55% an hour for the oldest drivers so that it is possible for any driver to be trained at 10x and recover in time for a race the next day.
I'm aware that not all of these are bugs, they are simply observations that should be relatively easy fixes and I would love to be as involved as possible in helping iGP.
