About the Nissan Skyline ER34 mod

So basically, I was just strolling on Google trying to find a Nissan Skyline GT-R mod, then I came across a reddit post talking about a Nissan Skyline ER34 mod that crashes the game. I know the OG post is deleted but I just want to reach out to them saying this: What happened to your mod, why did you delete it, and is it possible to fix it? I also saw an outdated tag on the archive of the OG post. I also want to say this, where is the updated mod? (if there even is one.)
