Random Ice tile formations?

[uraharakisuke]

I was playing around with a petrol gen and I keep getting random tile formations in the air. The h2 temp is around -73C and the idea is to use the ice as coolant in other builds. But I can't figure out how to stop this from happening. The mass of the tile varies from 500g to 750g and it happens randomly and quite often on loading and reloading.

 

I searched past threads and found this

 but there was no solution presented there. I read somewhere else that tiles only form when mass exceeds 200kg so why is this happening at 500g? or how do I prevent it?

I think this is a bug that can appear after loading the game. The only fix I know is to add robo miners that get rid of the ice blocks.
