People have been reporting issues with v8.0 since it released. I didn't know v8.0.3 was out. Honestly, I'm still on v7.6.0 and and it works fine for my modding purposes.As for how many people have had the same issue on a random Thursday, that actually did ring a small bell.
When I first tested Juiced on its own about a week ago - it was version 8.0.2. By the time I had followed your guide for GotR and assembled the mods I wanted for my actual playthrough, 8.0.3 had just come out 10 hours prior and I immediately upgraded to that.
Maybe 8.0.3 broke something and that's why?
But if there are no further issues to the ones you mentioned here, I believe you should be bug free now!
