Hi Zeek, you picked the right place to post, welldone.
When I uploaded the races, I wasn't able to upload the race type (Nitro, TT and so on).
TimeTrail Nitro
/resetmta 6 2 11
One World Upgrades
/resetmta 2 2 12
I really need to add some information on what each number does, but I ain't got time. Will soon though.
