Sorry for basically grave digging this snippet, but it seems that when the user puts in too many characters it'll make the bot just say something with the relay prefix. A short example is like:
<Known> Hellooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo
Then on the other end (the bot's relay):
<Bot> .:Known@Network:. Hellooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo
<Bot> ooooooooooooooooooooooo
I'm not sure exactly how to fix this, so I thought I might as well ask the creator (or anyone who is able to fix this problem.
Otherwise it's an amazing snippet!
Depends what the maximum count of characters per sentence the server allows. If it's too many, the server will break it down.
So it's not the bot, it's the server.
