I can go into the inventory and switch weapons and continue playing just fine. But when I hover over a weapon and hit triangle to pull up the details I instantly crash, it gives the error code weasel. I also get an crash during the opening mission where you pick up the exotic weapon. When I restart the weapon is in the inventory from the start and I can progress past the part where you pick it up fine now. Even after completing the first mission while in orbit I still cannot look at the details of any item without a crash.
