If you move your mouse wheel way too fast or its just too sensitive it wont detect any movement, Try moving it slowly

I have tried it still wont work

You can do the same thing using the keyboard, while holding a prop hold E and press W for forward and S for backwards

It is just a pain would be one of my my mods i got off workshop
