I made a modification to a GameSetting (Gameplay -> Settings...) in my mod (iAVDSkillStart) - then later realized that change was going to cause other problems. I found a way around needing to make the change in my script, but I cannot remove the change from the GameSetting.

I set it back to the previous number (default 15), but it is still tagged as a modified value - which means my mod will now cause conflicts with other mods which modify the value. If you change other values in the mod (such as a Race or Spell) you can simply delete the tagged item and the game reverts to the default. I cannot seem to delete the GameSetting though.

How I can remove the tag? Any help would be appreciated!

In the window you use to load your plug in file is a button called Details.

Click on that, then look for your game setting and delete it with your delete key.

Once you load the file after doing the above then save it and that change will be removed from your plug in.

The link I gave you is for the Oblivion but it is exactly the same steps.

Scroll down to the heading " Use The Details, Luke "

Brilliant! Thanks Spooky!
