I've had crashes on randomly loading games, and whenever I enter Vault 11, here is my Load order and mods.

FalloutNV.esm
Deadmoney.esm
HonestHearts.esm
IWS-Core.esm (Increased wasteland spawns)
Project Nevada - Core.esm
Project Nevada - Equipment.esm
Project Nevada -Cyberware.esp
Project Nevada -Rebalance.esp
Project Nevada -Dead Money.esp
Project Nevada -Honest Hearts.esp
IWS-AS-Low Spawns
Desert Armor.esp
Fellout.esp
PerkEveryLevel.esp
z_Fiends_2.esp (More Fiends)
Unlimited Companions

I had the Community Bugfix patch in there, but I deactivated it, hopefully that got rid of it all. Anyways, does anyone know if it would be my load order messing things up? Or would you say that's just how it is (specifically the loading games one)

About the load order, have you tried using BOSS for that?

Also you wont need PerkEveryLevel.esp, there's such a feature built into Project Nevada.

I just tried BOSS, it told me to update, than I did, than it said a problem occurred. Than the BOSS worked. Also, when I take off Perk Every Level, will that reset anything with my character?

Hmmm, it shouldn't. Just remember to toggle Project Nevada's on before you level.

Thanks for your help.

I need help again, i want to add the mod "Companions Infinite Ammo". I was wondering if that would interfere with any mods I have now?
