Okay, so, long story short, a friend of mine sent me a modpack of his so we could play together. I played some singleplayer so I could get the hang of things, but when I craft items from the "PrimalCore" mod, the game crashes and the log tells me it's a "Rendering screen" error. I looked around, every source says that it's an Optifine problem, but I don't use Optifine. So, I crash when I craft new items and my friend does not have that problem. Here's one of the multitude of crash logs I have accumulated, hope you can help!
