im having the same issues, now it happens alot during match highlights when my custom playlist will start. so its most likely the custom playlists.
listen to this, SO typical of pes, smh:
i get my first career start in become a legend, a wing back for genoa fc, my first career start is against inter, and i have my first career goal in it as well. im prettu much having the best game in my career, we end up losing since it was the 2nd leg of the cup match and inter wins 3-2 with goal total. and when i go see my rating which i predicted would be in the 7's, the game freezes on me. my patience is running thin with this game, i dunno if i can keep supporting something i love if it wont love me back. and dont even get me started about the online mode
