Landscape is really messed up on my world

I can't really explain it so I took a picture



Anyone have any idea why this would happen to my world??

 

I can't see the picture

Try that

 

Is your server recently chashed or something?

 

Not that I can think of. I run the server on creeperhost.net and I did reset it once for a plugin. Other than that I really can't think of why this would happen...

 

Is your server recently chashed? Dis you get a "world not in gzip format" error?

 

nope I don't think i got that error

 

Meh, Looks like a glacier just passed through

 

Perhaps you updated the server from one version of mc to another? This happens when there are changes in the world generation code of minecraft.
