I've done a nice lap and save it to hotlap.
I remember I already set the tyre grip to 100% before start the hotlap.
But when I use the original decrypted GP4.exe, my car ran out of the track.
If I use GP4.exe which I used to make that hotlap, it's a perfect lap.
I already check my GP4.exe that it was 100% tyre grip before I do the hotlap and when I watch the hotlap.
Is this a bug in the GP4 Tweaker? or is it something else?
