I'm still troubleshooting it. I downloaded a brand-new newliya file, loaded the game with only it active and nothing else, and the problem was solved. Tried with a few UI mods, and still no error. But when I loaded all my 200 mods, there's the error again. So I'll have to separate my mods in blocks and test per block... I'll probably be finished by Christmas, but that's because I have work and uni and can't focus 100% on Beam. But don't worry, I'll report my troubleshooting here.
