Unable to change prefix

[pashalecqua]

Bug Description

The bot works perfectly fine with "@mention" but when I try to change it to "le" or "pls" it fails to work at all, but then works again when I switch it back.

Steps to Reproduce

Change the "@mention" to "le" or "le "

// This sets the prefix for the bot
// The prefix is used to control the commands
// If you use !!, the play command will be !!play
// If you do not set this, the prefix will be a mention of the bot (@botName play)

prefix = "@mention"

Expected Result

I would be able to type le play x and x would play
