I want to change the effect of +1 Charisma from the Armor of the 87th Tribe to +3 Endurance, but when i go to close the GECK and save my changes it asks me to select a plugin file. If I try to select the esm file for Lonesome Road, it says that can't be done as it's a master file, which is fine. I try to use the bsa file though and the GECK will freeze, my loading cursor will pop up, and the GECK will minimize, sending me right back to where I was. I've edited object effects for other mods before such as the effect for Marko's Coat from New Vegas Bounties 3, I haven't done it with a main dlc or esm in general before though. How would I go about this? Edit: I was able to edit the object effect of the Sierra Scorched Power Armor when I was using dragbody's Fallout 4 Power Armor mod. Even more reason for why i'm so confused.
