These are the mods I have installed, and the script lag is only present when DU is activated. I don't think DU is the culprit though, and instead think that some other mod is causing issues with it, though I can't for the life of me figure out what that is, as even deactivating all other mods does not fix the problem (so I think it is a mod that makes a permanent change to the save not removed when the mod is deactivated).

If anyone has had similar issues and found out the cause of this, I would very appreciate you taking a look at my modlist and seeing if you recognize the culprit.
