I have raced 95 and 96 seasons of the supertouring mod. When I raced at Oulton it was always easy win because of this. I tried in the race event mode and it was the same. The drivers pitted on last lap. Tried shorter races, the same. Used forced pit stop and then they stopped twice plus in the last lap. I tried changing the fuel use to track length x16 and nothing changed. In the original version I don't have these problems tho. It's only on the trackpack version.I race Oulton using the the super touring mod (usually 97,98,99) and have never had that issue.
What cars were you using?
