I'm using Fallout 3, i was wondering if Skyrim or other games don't have form id's for all their plugins.

in fo3edit, its showing no formid's / Null Reference in the File Header for every plugin, so when i make a merge patch, it seems to work ok, but gives the in the Messages window after all the masters are added.

I don't remember if this happened in Skyrim/Oblivion/New Vegas, Just wondering if it's an issue. Thanks for the help.
