For context I am doing a mixed class race of 43 cars at the Daytona RC. Everything from the IER Porsche's, IER P13C, IER DPs, URD GT Cars and a handful of stock GT cars. (essentially trying to replicate a 2014 Daytona 24 minus the PC class). 12 Laps into the race of 70, half of the cars run out of fuel. I am running with a 2x multiplier for fuel and tired, and a 12x multiplier on the clock itself. I have verified integrity of game files on Steam and this still happens.
