where you guys at the moment? Im staying at 95,xx %, have to do the freaky monsterjumps, knife flights and under the bridge side missions. I hate it... you crash (die), waking up in the emergency and pick up your plane / cars / bikes again and go back to that last spot. It always costs you a lot of time even when you take a cab to your hangar.
Especially the knife flight missions are really hard to make.
