for spawning drones, while(max_drones()>num_drones()) so i can send in all of my available drones
Within Drone Hunt I'm using a countdown before the clone moves randomly (seen below) so that spawned drones don't follow each other and to avoid getting drones stuck in a loop.

r=10
compass=[North,South,East,West] #above with first dir

if x==x2 and y==y2:
#same code
elif(r>0):
#same code
else:
	idx=(random()*len(compass)) //1 
	move(compass[idx])
	r=11
r-=1

note: if you're planning a reuse 300 times, I don't recommend setting r to a higher number since hedges vanish, making it more likely for drones to get stuck in loops

I'm also using: use_item(Items.Weird_Substance, (get_world_size() * 2**(num_unlocked(Unlocks.Mazes) - 1))) to spawn the maze at the same level of world size

and for the recycling farm achievement, i've adjusted both if treasure to say:

if get_entity_type()==Entities.Treasure:
	use_item(Items.Weird_Substance, (get_world_size() * 2**(num_unlocked(Unlocks.Mazes) - 1)))
	if get_entity_type()==Entities.Treasure: #assuming next treasure doesn't spawn in the same location
		harvest()
		return 1

i've successfully done a 32x32 reuse maze 300 times using these adjustments.
Note for room on improvement: change my random movement to an "move closer to chest" to improve runtime
