I’ve had to play the final battle twice now, because the game keeps crashing when the bullets are dropping after the firing squad fires during the cutscene. The first time I beat the final battle I got the Eridian Vanquisher legendary for my character, Wilhelm. The 2nd time I didn’t. I was very angry after the first crash and I got back into the game only to find I’d lost that legendary.
This is on a PC with Windows 7 Home Premium 64 bit.
Edit: After verifying integrity of the cache on Steam and rebooting the computer I was able to get past this cutscene. So I guess 3rd time was the charm in this case. Unfortunately I still getting get that legendary class mod to drop again.
