Hello, I've tried playing awakening on singleplayer, and it works just fine. However, when I play on the server I get constant x-ray vision(blocks disappearing and becoming see-through) or the blocks momentarily turn into other blocks or 2-D images. This, combined with the periodic fps drops make it a real pain to play for any amount of time. I'd be really grateful if someone can tell me how to fix it. Note: The only extra mods I've added are Optifine and fastcraft, and as I said before, singleplayer runs just fine. Thanks.
