This works for me on server no.9. My server is old and is in good shape, I rarely have a problem with anything. I just played CL Final for my friend as he could not attend, he is server 89 and its complete mess. During the CL Final in 34th minute to go into penalty shootout and do some **** is unacceptable. I won it at the end but this should NOT happened..... Nordeus wake up !
