This instant crash has only happened to extract that tests really high 90s. It will only drop out this fast if I don’t apply any heat on the jar. I haven’t seen any issues with Medusa yet other than when I crystallize at a lower temp in butane. My take on what’s happening is that just like in water, when you freeze cold water you get air bubbles trapped in the ice that make it cloudy. If you heat the water first, the air rises out of the water and it produces clear ice when it freezes. I think the same is happening here. When crystallizing that cold, butane vapor can get trapped in the lattice of the diamonds and when harvested, that’s when the solvent starts to expand and cause the lattice to crumble. If you crystallize in a hot environment, the butane vapor is forced to to the top of the vessel thus preventing any solvent vapor from being trapped by the crystals
