/* ================== */

/* I think this is where the problem is it is meant to randomly place 4 'peope'
but it can only place it in spaces that dont contain the base camp or lava
I have tried to set it up so that a new person is added only if the random coords
dont match the coords of the base camp or any lava squares but it doesnt work
any ideas!? Help appreciated!*/
