This makes sure everything downloaded properly and tends to solve a lot of issues pretty much instantly. If you have not done so recently, I highly recommend that if you use Steam to run Rimworld, that you go into your library, right click Rimworld, Properties, Local Files, Verify File Integrity or whatever it's called. Credit to Felinoel, Chevalier XLIV, and everyone else from Rim of Magic, Madness, LotR, and a few other servers who helped me figure out (and post) this entire mess of a guide, and the intricacies of modding with Rimworld in general, over the course of like.
References to 'I' or 'me' are because I, Trisscar, the author of this modlist guide, finally got off my ass and went in to add explanations and flesh out the guide, as before it was short and terse due to Discord's character limit.
