OKAY UPDATE.
The dorrknob is KINDA fixed. Thanks to Kelvin for coming to save us from the 'monsters'. [ according to don ] * CLAPS FOR KELVIN!*
Actually, he changed the doorknob back to the old one. Cause some metal part in the knob got bent and stuff. D:
BUT, the door CANNOT be locked now. SO REMEMBER TO CLOSE THE DOOR AFTER YOU LEAVE ROOM THANKS.
