have loved this game from day dot but now it seems the more i upgrade and get inside top 3 it starts to glitch and will all of a sudden lose speed like youve taken finger off accelerator button so you lose load of places, needs sorting as this was a 5star all day long but is annoying me so much now it happening so often and b4 you say no its not my screen as its perfect condition, pnly just 4 star now but will lower and then delete ap if carries on
