Should most random terrestrial planets be covered in ice?

It seems all terrestrial planets spawned by the add tool insist on being covered in ice.

Changed the subject to:
Should most random terrestrial planets be covered in ice?
... as 'Common Bug' is really vague.

I agree it's probably too requent... how often should a random body by ice covered?

Dan, ice dont melt even near the sun.

Different issue, can you provide reproduction steps? Something like:

- Home > Solar System
- Click Add > Earth
- Click to place Earth within 0.1 AU of the Sun

Heres how.
Add some icy objects then place it few kilo's around the sun.
the temperature keeps -261 C and the ice dont melt.

I can confirm that the random planets seem biased in favour of  low density ice (~2.3) It does melt, however, it just takes a little while. Proportions of 40 - 50% water by mass are quite common.

However, in a quick and dirty sim, they all melt, as does a 100% water ice object (which ends up as existing solely as plasma but takes on its original terrain map. In this case it was built off Mars, so it becomes mars.)

no but.i put the time on 1 yr a sec.

I think I found out the problem.

Not ALL planets are covered in ice, just the ones with water. I can't find a way to melt the ice other than bombarding the planet about 30 times with Ceres. 

And on top of that, when I raise the temperature, the ice starts melting, but if I click out of the text box for temperature the planet goes back to being NEGATIVE KELVIN. I've also had issues with this in US1, where the temperature just goes back to it's original.

Whenever I start a saved simulation my starts off at like -100 degrees Celsius and warms up to 5 degrees Celsius. Have you tried waiting?

We're still working on the handling of planets with water. This should get a lot better over time, and in the coming Alphas.

You can also expect some oddness with the temperatures, as the simulation is controlling the temperature in most cases. If you change it with the UI, it can have some odd behavior.
