Thanks man! The most damaging of these bugs (the end-of-champ car stats thing) was introduced in one of the updates, I mistakenly commented out a crucial bit of code. That will be fixed in 1.0.6. Also, I figured out why screenshots are being overwritten and I'm fixing that right now. The safety car issues, I'm mitigating, with some rebalancing of safety car speed. Please let me know if this remains a problem.
1.0.6 should be live in an hour or so.
