I rechecked my load order and the merged esp's for the additional weapons look to be in the right spot. They're right after the Project Nevada EVE and WMX patches and also right before the Enhanced Blood esp. I also checked to see if the weapons worked if they were loaded in a non-merged patch and they work fine like that. I don't understand why a merged patch would make a difference? Edit: Also the weapon mods for the new guns are still showing up in doc mitchell's house, as they should, if that's any help.
