unfortunately nitro races seem to be bugged and, they transform nitro to some other races, hopefully it will be fixed, till then use nitro button ONLY on races where nitro availability is ANNOUNCED WITH BIG TEXT ON SCEEN, if u are seen using nitro somewhere else ur getting ban
this text is not only for u, its for everyone else that do the following too!
about unban, i dunno ain't my thang i have nothing to do with it.
