I'm having issues with the way pressure is handled.  It seems like pressure is handled like heat in the simulation, which makes sense as a quick and easy way to simulate how objects under pressure would act (poorly worded, i know) but that also means pressure can be transfered through literally anything, meaning you could have an entirely closed system with high pressure inside it and say powders or liquids outside it, and then the second the pressure reaches the shell containing it, it 'conducts' through and throws away any non solids.  pressure also influences velocity way too much imo, a tiny one or two pressure can basically level any save that isnt completely solid.  I would just disable it but I need the pressure there because it causes really intricate reactions between molten elements that are hard to make manually, but its hard to not disable it because as I said before, it somehow conducts through solid objects sometimes.

Sorry if it sounds kinda ranty, im a bit chuffed by my saves getting detonated by the wind
