There is a mechanic that allows small amounts (~5kg) of resource to instantly change phase if next to a tile above/below this tile's phase change points. For example, ice next to warm air will sometimes "bleed" 5kg puddles, large block of water will "burp" steam if next to a 150C tile (even if the water itself is cold), dirt may drop small blocks of sand. @Kabrute said it also affects liquid O2 next to abyssalite tiles, suggesting it ignores heat conductivity. Did anyone do science on
