» Thu Jul 07, 2011 10:11 am To search for errors, you will need FNVEdit. Load all your active modules (which is its default load selection). If it fails to load all of them, then you need to sort out your module mastery issues. Once you're all loaded, select all modules (just ctrl-A), and then deselect FalloutNV.esm, and all your DLCs (preorder DLCs are small enough not to bother with deselecting, but the big ones are not small enough). Once you have them loaded, right-click and select "check for errors". Now, this will spit out all sorts of errors into the Message tab, so you'll have to sift through to find the ones that indicate a FormID displacement error.
Here's an example of what you're looking for:
Checking for Errors in [3B] Playing With Firepower - New Vegas.esp...[00:10] RCIL - Effect -> Found a ACTI reference, expected: AMEF[00:10] Above errors were found in :Ammo Effects[00:10] Above errors were found in :a0aSECLreflect4 "Energy Cell-L, Reflec Mk4" [AMMO:3B010218][00:10] Above errors were found in :GRUP Top "AMMO"
It found an error where a reference field was expecting an AMEF form type (AMEF = Ammo Effect), but found an ACTI form type instead (ACTI = Activator, a type of interactable world object). What would happen in-game could result in it simply not working, or it could result in game crashiness, depending on the whim of the game engine.
It will also turn up a lot of other stuff, mainly stuff pertaining to flags and whatnot. You want to focus on "Found a (ABCD) reference, expected: (WXYZ)", where (ABCD) and (WXYZ) are the form types. In the event of such an error in a leveled list (LVLI, LVLC, LVLN), then it could have a huge list of expected form types, like this example:
[00:12] Reference -> Found a REFR reference, expected: ALCH,AMMO,ARMO,BOOK,CCRD,CHIP,CMNY,IMOD,KEYM,LVLI,MISC,NOTE,WEAP
COMPILED OF THINGS AFFECTED
PLAYING WITH FIREPOWER by TheTalkieToaster
Playing With Firepower now has several Ammo Effects now improperly pointing to Activator forms.

Since these are just out of my own personal load order, others may exist. If you decide to sift through your own mod load for FormID displacement errors, please paste the error reports in the manner I have here, within Code and Spoiler tags to keep the post length down, so I can add them to the list.
Looking at them they weren't updated though.
