as far as those of us people having freezing before starting multiplayer, Game crashing when certain things used or accessed or game slowing to a crawl while HDD accesed... Maybe some of you with these issues can state whether they are playing from a WBFS partition, Fat32 or disc.
Likewise maybe some of you who have no issues at all could state the same.
It may be an issue of accessing the hdd for some of us. I know the hdd is usualy working hard for this game but maybe it could pinpoint one issue.
I am still using the WBFS method but will try turning it into fat tommorrow-ish. I also have tried my original disc which at first didn't work until i updated ios57. Everything except multi online would work.
