Creepers

Okay thank you...Although i liked it from when you were able to get raw material from anywhere (Except bottom)

I have reproduce this error

re read th ticket

I know how to fix this problem,
First go into %appdata%

Then go into .minecraft folder

Then versions.
C:\Users\ \AppData\Roaming\.minecraft\versions

Click on a version and look for "version name".json (I.e 13w16b.json)

if not there copy and paste
to a .json file within the version u want

Change\/ id \/ to whateva u want
