I bought the game.
I play on Windows 7 64bit.
I have 8gb of RAM.
I have my own server for friends and family.
Here is my internet speed:

My java is up to date and I had no problems with the game so far.
So the problem...
I host a server on the computer I play Minecraft on. So I'm playing.. and everyone knows how buggy it is. Anyways, so I crash from a random error from the server or the game, doesn't matter. After restarting, I get errors when I start my server. I do some research and looks like the saved file is corrupted. I open up MC Edit, copy the new buildings I made into an old copy of my world I had as a backup. After doing this, I start the server with the fixed map and it works well.
After days and weeks of playing, I had to do this 3 more times from random crashing of my computer due to running the server or playing the game.
So now... after building around my spawn point for a long time, I go and explore the world around me. And I see this:

http://img204.images...worldends2.jpg/
http://img340.images...worldends3.jpg/
This... thing goes on indefinitely. It successfully ended my world with vertical cliffs... I've been walking at the edge for a while and I haven't seen the end of it yet. Also, this is just one side of the map. I think this is North from where I spawn... but anyways, the point is I haven't looked at other sides to see if I am like trapped in a square. Know what I mean? So far I hope it happens only on this side so I can explore on the other remaining 3 sides, but if the other 3 sides are like this, then I am basically in an island surrounded by indefinite cliffs....
Any solutions? If not, at least Notch should see this..
Thanks for looking.
