Steps to Reproduce:
Open the game
Input command "/me 123: .."
Observed Results:
The print info is: Syntax error: Unexpected "": at "me 123: ..>><<"
It seems the command like "/me [string]: .." cannot run correct.
Expected Results:
The message is successfully sent to the chat.
Note:
Type a Space char between the char ':' and the string ".." .
This is probably because the game uses : and .. as something else. Put your message in quotes "" and it will work. Don't worry, the quotes won't appear when the cmd is executed. This trick should work for any text parameter.
