Hello, i was on world buy and i wanted to Paste a selling message that i preparated, so i type CTRL + V to paste the text, and the game crashes. I tried several times but the result was always the same, I too see the controls settings (cuz maybe CTRL is for exit), but nothing. Message: 
!Christmas Sales!Selling all i wear, take your offer!
Does it happen constantly?
