I have similar problems to many people with the single player aspect of the game: The game crashes straight after defeating the end boss. (Trying not to spoil the game for others by giving the plot away).
I have attempted to get support through origin to no avail. I have also tried to open "chat" through EA / origin's site only to be given a window offering me a 6 hour wait (no joke) for assistance.
Origin either doesn't seem to be aware of the 1.1 patch, or just won't download and install it. In the patches release notes it states that this crash is one of the bugs fixed, but I don't seem to be able to get it / install it. . . It's all highly frustrating.
Is anyone aware of a different source for this patch or aware of a way to force origin to update? I have tried right clicking and choosing "check for updates" as well as "repair install" which found no errors, but still didn't install the patch.
Like I say; I would be grateful for any help at all.
Many thanks.
