I just updated my tekkit to 3.0.3 and converted my world to "anvil" or whatever. and when i go into the world, it says "generating terrain", "simulating the world for a bit", and all of that. But when i go into my world it shows my inventory for a brief second and then says "saving chunks" like it would when i just exited the game. then it crashes. Error code: I coulnt tell because it just flashes on my screen then goes white and i exit. I really hope someone can help me, as this is really annoying. thank you.
