Lilypads on Lilyponds

[skittles sour]

A bizarre thing I've noticed is that when you create a room with the value of LILYPOND, lilypads would spawn even if you did not include in the static layouts (which is what the rainforest lilypond rooms do), for example, for my kraken pond I have:

AddRoom("kraken_pond", {
	colour = {r=1.0,g=0.3,b=0.3,a=0.3},
	value = GROUND.LILYPOND,
	tags = {"ExitPiece","Bramble"},
	contents =  {
		countstaticlayouts={}, 
		distributepercent = 0,		
		distributeprefabs = {},
		countprefabs = {
			kraken_spawner = 1, 
		},			                
	}
})

And when I spawn the room, the kraken would still be sitting in the middle of lilypads. What is making the worldgen do this? And how can I stop the lilypads from spawning?
