Anyones know a good anti crash for props on the gmodstore I can buy?

I made this a while ago. Might be worth checking out.

It's not that long ago... the script is still quite new I'd say. Anyway, I use it and it's good so I recommend it too.

thanks cuz i was using apg and someone joined and was flyiing by using props

After using it for a few days i realized your able to crash the server with the classic way of stacking chairs. Is there a way to fix this?
