Heat pipes and heated buildings would melt the ice, so to protect the ice that keeps you floating you can place concrete (or refined concrete) as an insulator. In practice this just means that most entities can't be placed directly on to ice, we don't actually turn the ice tiles into ocean... anymore. That used to be a mechanic, but it was too annoying to deal with when you try to build in an already heated area.

This mod brings back this scrapped mechanic, allowing you to play on Aquilo as it was first meant to be.

Ice platforms and smooth ice will melt when they get too hot. It's also possible to build on them. Still requires concrete if you don't want your structure to sink into the cold cold waters of Aquilo.

Contains settings so you can enable/disable the tiles melting or being able to build on them, to make it as easy or as hard as you want.
