How Can I dupe riot 4x with trucking method I try entering pizza and do moster 8x but it failed so can anyone explain me

1. What does riot x4 have to do anything with monster x8
2. What has failed exactly and at what point

Details, please

1. Sorry for My bad writing I mean I tried with pizza menu method.
2. I see monster X8 is possible due to trucking so I tried the same and the pizza menu disappear once I leave the place

Also I noticed that duping riot X5 times could be considered a completed run due to the phone call you get after riot completion (it's same as the phone call after EOTL obviously I know this doesn't valid)

The answer to any question like that you might have is most likely "too slow" or "would crash the game". Starting mission x during mission y is technical and I doubt you want to read about the details.

Nevermind I find out that in order to keep pizza menu you need to bind sprint and accelerate on same key
