Okay, so couple times now the game has randomly crashed with no errors. it just closes itself. it seems to happen after around an hour of play. both times i've been walking around when it closed. Once on ultra, and once on High settings.

Intel Core i5-2410M
nVidia GTX 560M (Patched with the BF3 Beta drivers, other than that its unmodified)

It's not really too big of an issue, but its annoying having to repeat 10-20mins of playing..

sorry for double post, but when i started the game up again after the last crash, i noticed that Dolphine for some reason had become hostile... so i can't complete the Diplomatic Immunity quest.. I spoke to the Wood elf, and when i went to meet up with Dolphine she instantly started attacking me. i tried to forfeit several times, but i just ended up dead every time.
