Im not exactly sure when/why it happens
the script does what its meant without any problems except the crashing, you can spawn and read it but seems to crash fairly regularly when i try it on the server.
Ive tested it on lan and tried to cause it to crash but ive not been able to.
Ive tried getting 2 people to read it at the same time, but thats ok.
I doubt its the actual create_note code because thats mostly lightly edited tripmine code.
Could it possibly be anything to do with the player name / message that they've entered?
