I'm at the wiki site for enabling support for Fallout 4 mods: http://wiki.tesnexus.com/index.php/Fallout_4_Mod_Installation The instructions are a bit confusing to me. Step 7 says to open Fallout4Custom.ini with your favourite text editor. Step 8 says to add the lines to Fallout4.ini [Archive] bInvalidateOlderFiles=1 sResourceDataDirsFinal= The way I'm reading it, is that you leave Fallout4Custom.ini alone. Open Fallout4.ini and add the lines. Right? Also is there supposed to be a value at the end of sResourceDataDirsFinal= ??
