Rocky planet with 100% water atmosphere... What?
Atmosphere type: 100% Water

It's a sauna world 
Yeah it's probably vapor, but it still looks strange to me with 1.8 bar pressure on a 0.02 earth masses body.

Neither the temperature nor pressure are enough to reach supercritical liquid water. Temp should be 373.946 °C (647.096 K) and pressure should be 217.7 atm (22.06 MPa).
But as my ex uses to say: This is not a documentary.

This.
Our atmosphere is a mixture of oxygen, water, nitrogen, etc. It's still in a gaseous state.
This atmosphere is just water. It doesn't say 100% liquid.

Aye, but t'was worth a shot all the same. You never know, we keep finding weird planets out there that don't perfectly fit our models for what they should look like based on what they're made of. A planet's history defines its characteristics as much as its base components. Unusual heating patterns and tidal forces on that locked moon with such low mass and density, yet a dense and steamy atmosphere. Makes you wonder if we're seeing game bugs or just something we haven't discovered in nature yet. Most likely the former but I bet you my life savings if you went far enough in any direction you'd find Lacewing's sweaty moons out there somewhere.
Solid water, riiiight sure it does, I think you're treading on thin ice with that one mate.......
I just looked up and like Midian Cabal already posted, you need more pressure and a higher temperature to reach the supercritical (overheated) state, so it should be just water vapor. But calling water vapor just water is as irritating as calling water ice just water.
It just seems wrong that there can be a water vapor atmosphere with relatively high pressure (1.8 bar =1.8 atm = 180kPA) at this temperature (610K = 337°C) on such a small moon (1.19x10^23 kg).

From the scientific standpoint taken by the system map, describing it as water despite the temperature is correct.
And yet we have ice planets
But not ice atmospheres.
Saw a world with a surface pressure of over 1,000ATM, yet it has 0.1 Earth mass, which is kinda impossible! If the world has a liquid surface, that is not an "atmosphere" since aerosols of some nature will be present, and that's the atmosphere...
Same goes for "100%" metal (!) worlds, kinda funny, but essentially impossible.
The Stellar Forge does make a few mistakes...

Those planets must be made of pure Dragonforce...
