Major Crate/cart + gravitron + trip laser = rip server

[NateTheSquid]

the 2 crates is what caused the lag, not the gravitons. 12 at once should be a barely noticable spike, but launching two crates, I assume on while tile, at the same time, would be a pretty big spike as they try to interact with eachother as well as fly forwards. only use 1 crate and probably a max of 9 gravitons on one tile.
