Skript CRASHES server

[Pryzmm]

I dont know why but these couple of lines crash my server. Nothing loads and eventually it stops.

on join:
	while player is online:
		if {GensToggled} is true: # Variable checks if gens are enabled or not
			loop {GenSpeed} times: # amount of seconds to wait
				wait 1 second
			loop {GenLocations::%player%::*}: # finds all gen locations
				set {_Number} to loop-index # ID of variable
				set {_DropType} to {GenDrops::%{_Number}%} # Item that drops
				set {_DropLocation} to loop-value's location # Location of where it drops
				add 1 to y coordinate of {_DropLocation}
				drop {_DropType} at {_DropLocation}

There is no delay if {GensToggled} is false so that is why its crashing.
