Command bugs

Command name

customcom create random

What cog is this command from?

Core

What were you expecting to happen?

I tried to create custom command with a random output, without filling in data I wanted to exit() the command maker.

What actually happened?

How can we reproduce this issue?

Add a custom command with random output, instead of adding data just exit() it.

Exception in command 'customcom create random'

The above exception was the direct cause of the following exception:

I saw this issue before and I'm a little surprised that it wasn't reported on our issue tracker yet, so thanks for the report 😄
