Ok guys let's hope this helps:
I had the same issue, let me give u my situation first:
First of all i have the edition with Bruce Lee, I created my own Character in the menu, then used it to play Career mode, all worked well.
I decided to start over and changed my character from balanced to striker and changed his celebration to the bruce lee one.
Thats when after winning the first game i froze just like anyone else here.
Changed the celebration to another one started over and it now works fine again.
So for me it was only a problem when using Bruce Lee celebration it seems.
Lemme know if this helps.
i just bought the game this past weekend, was super excited about playing a new career in order to learn all the controls and of course, i wanted to be the baddest man on the planet in the octagon, but i couldnt even get past the first fight because once i hit "recovery" it freezes, this issue is still occurring folks
so i just tried the Create A Fighter and then Import A Fighter workaround, and that gets the Career Mode to work correctly, im 9 fights in, now about that AI.... that's another issue for another thread
I had just recently purchased UfC 3 icon edition and it was a whole lot of fun up until it started freezing. I have tried all of the "tips" for the freezing game and crashing in career mode. I have made two characters and both came to the same conclusion, they both ended up freezing. The whole game crashes once one person, either the opponent or myself, throws a punch. I was wishing to fully enjoy this game because I have played since UFC the first one that ever came out and this bug is just ruining the game not only for me but also for others in the community. I only wish that you guys start looking into this issue because your fanbase is slowly dying. I know that you guys have ignored this issue. because people have been reporting it since the release and now its July and the freezing glitch still occurs.
Sincerely, Ex-fan of UfC
