I don't know if it's a bug or if you changed the physics in the game but all the press forward parts are broken, I was mapping a map with a press forward part, it does not work anymore, and I tried to play another press forward map to verify if it was the same and indeed the PF did not work.
Hello!
Just to make sure I understand correctly - are those parts simply having no effect on the car?
If this is an issue that is affecting all PF parts, we can certainly take a look!
