I have been having this problem 2 month before and i had not report about because i think it will only be urgent quest problem but have not problem to the story quest, but now i am having some progress in the story quest and the problem appeared in the story quest which is fighting Dark Falz Luther. Same as always , i can cleared the first part of the quest. When i exceeded to the next part which is fighting Luther , the game will freeze at loading and crashed. Its appeared too many time in the game when fighting Luther relating quest. Now, i had not idea what Luther Stage look like cause i did not have any chance to proceed the quest but keep crashed. I hope this problem can be fixed as soon as possible before the update to episode 4. I think there are also some of people like me are having this issue. Please fix it ASAP, thank you.
PS. Sorry for my poor English grammar.
