Using no mods whatsoever cept for this one.
Thank you for saying what caused it though, we will take our precautions and try avoiding it.
So far the script is very great and stable for us, IF we're careful.
A crash also happens when in multiplayer, a person will drag a suspect to his vehicle - during this time of period, he will usually crash and have to restart the game.
Thanks for all the help guys, really appreciated. :) Can lock this now.
