So I deleted the catchup file and liked how things were going. It seems without the file you won't get ai posting crazy laptimes as soon as they're close to you. I actually could create gaps with ai, and when I was overtaken they didn't run off into the sunset instantly. Tbh I have no idea what the file actually does, but ai in race seemed a lot more...natural. Sadly, deleting the file seems to make me unable to save any progress . Anyone found a solution to this? thx PS. I have backups but would really like to keep playing without the damned file.
