chunk loading errors

Chunk error? Random Blocks Appearing--but walk-through?

On servers when I get on if I fall i keep falling and eventualy die

Command block minecart keeps on killing! I really want to get back into my world please help! how to reproduce. 1) get command block minecart 2) put an activator rail. 3) u will die continuously!

When I use a music disc in creative mode (gamemode 1) I put one in and 64 (in a stack like inventory editing does) came out! It is getting on my nerves.........

This is the weird seed. 1100924296 at 946x , 55y , 357z w/ coordinates. but if you go to the nether the sky is RED. I mean blood red!!!!

I can't destroy blocks with a sword.

When a creeper explodes my nether portal it doesnt explode the whole portal (the purple stuff) it just destroys part of it. How to reproduce. spawn a creeper next to a nether portal. then make it explode. It should not explode the whole portal.

When I go on soul sand, 1) the sky turns dark. 2) my hand also turns dark

When I sneak (Lshift) My hand goes down. (bottom right corner)

When I use TNT, you normally see it flashing and then soon explode. But mine doesn't flash, it just dissapears then reapears 10 seconds later exploding! It is ruining my redstone and seems to be more powerful. Please fix!
