^ Actually i forgot how to remove it..
go to Trigger editor > Delete melee initialazation trigger )
delete currently spawn mark on your current map..
find Spawn point : go to LAYER > unit > search on Building you will found Spawn mark
then put it into place where you want (after finish loading the game the screen will start at that place)
put all spawn mark for all player 1,2,3,4,5,etc in one spot (Stack it in one spot)
