Well, for me, the mod crashes randomly when I place any particle - liquids and gasses immediately, photons, neutrons and solids after a while and so...
Ok, it works now. Another "bug" found - Newtonian gravity appears to be not working correctly, sometimes liquids behave like without any gravitational force appealing on them. Also, sometimes having Newtonian gravity turned on causes teleporting particles to the left (and mostly upper) part of the canvas. And then making them dissapear.
@me4502(View Post) I found it when playing with the Wave Generator save. THere are GPMP that are supposed to move the water (they do so in vanilla TPT with newtonian gravity on), but the water just stands still and doesn't move.
