Bonsai Trees version: bonsaitrees-1.0.5-b77.jar
Forge version: 2760
I am not using Optifine:not install

Description of the problem including expected versus actual behavior:
I have cheats enabled and i can switch between creative and survival but when i use
/bonsaitrees generateMissingShapes yes
I get the message i do not have permission to use this command

How do you give OP settings in a Single player game then tell me this
I went into the Single player world and typed /op and i get the message this is not a unknown command so nope cant do this command in a single player game and why would i need to have to have the permission to send server commands, i.e. be an Operator in a single player game which i am using to do the command in

you do not get a console window to give /op or /deop when your in single player game you should only have to have cheats enabled which i do and that should give you full access to everything

You need to have the permission to send server commands, i.e. be an Operator.
