I've just about given up, I reached the final mission(I chose revenge) and I'm stuck. When I launch off the ramp and grab the helicopter I can't seem to be able to climb in. It tells me to tap A but nothing happens and Pegerino gets away every time and I've tried around 10 times now. Has anyone else had something similar? I can also try the chase after Dimitry if neccessary since I did the deal mission later just to see what the difference would be.
