Certain props cannot be copied, but will increase the prop amount.

[Danct12]

Copy a prop with +copy, certain props cannot be copied for some unknown reason.

so if you do +copy and doesn't paste, prop limit increases?

[Danct12]

Actually it does register as a prop and increases, but nothing being outputted.

Probably add something that checks if prop is there every once in a while.
