I just had a quick look, several cars were spawning in the pits on race start and coming to a halt a short way down the road, instead of spawning on the proper race grid.
It's being caused by a new checkbox added in CSP 0.2.4 and above thats flagged on by default, "Fix missing or misplaced spawn points". Turn that off and the cars spawn in the correct grid spots and take off as normal...so its another CSP quirk thats messed something up, not anything Fat-Alfie is responsible for.
