Can you tell me what is going on?

That server does not even have forge installed.

Oh, I was confused.

 

OP: Can you tell me what is the problem?

But it happened only in my world named Minecraft Capital City which is the city I am making . Yet, I made attempts to fix this issue using MCEdit.

You do not have Forge installed, this is not a FOrge issue in any way.

You say it's the world thats corrupt, delete the world and start again.

We do not support vanilla here. Because we can't be responsible for all of the bugs in it. We support Forge.

There is nothing we can do for you.
