Question About Rimworld Code Lingo

[Nordic Hunter]

Hey! Apologies for my newbishness but I was wondering what Rimworld defines as "Resolve References." I'm using quite a few mods for my game and I'm also using "Startup Impact." SI is telling me that the majority of the loading time is coming from resolve references and I was wondering what resolve references include or define. Do they have something to do with errors or information pathing?

If they are what I think they are I was considering creating a mod to help drastically reduce them to lower loading times, if not it is what it is.

Thanks, -Nordic.
