This is definitely not what is causing the crash. I have 99 key cards/alternator/distributor cap and area loads are fine. It's probably the infinite health option that's causing the crash as I find that leaving it on during area load often leads to crash. I suggest you turn it off before entering anywhere that needs loading.
@Draesk You can turn in the skull kill items to Sally in Wellspring bar.
@Wade58 Once you kill a bandit car, check your inventory and the skull kill items should be there. It doesn't notify you or appear as a pickup item.
