This is just additional information regarding the problem.

The top image is
deepocean.set("height", -1.999)

The bottom image is
deepocean.set("height", -2.0)

I'm failing to understand the problem here. Any help is appreciated.

I dunno man, that's Minecraft, not me. I guess things get wild when you set the base height to 0. I'd recommend not doing that.

Ah, that's a shame. Thanks anyways tho

By the way, in case you didn't catch what I was asking about, I meant that the ocean height doesn't drop at all unless I drop it to -2.0. Is that intentional? Does the mod only work with integers?
