Mario Kart PC Anticuts???

OK so I was playing DS Mario Circuit and when I took the jump after the dirt section (onto the part with the piranha plants) I fell in the water to the right and was placed at the FIRE PIRANHA SECTION!!! Furthermore, Lakitu was constantly waving the "reverse" flag for the rest of the race even when the lap counted.

So...

Does anyone else know of MKPC checkpoint anticuts?
Let me know
