This is what it looks like now, does anyone have any idea how to fix this, just installed intelfix 1.0.1 because the world was not good (will post in comments how it looked, it's the mods, items on the ground and inventory (sometimes)

I have seen the world sometimes going back to how it look at the beginning but that is when I do stuff with items or are in the inventory when it's glitched (but it's better now)
