      1. One block of lava to move cause 36ms lag spikes.
        What about more? what if 200 lava are moving at same time in nether/caves?
        when they are in caves they cause lighting updates
        is its okay to give 30ms of frametime to single lighting update?
        Reproducing with large quantities is hard because player can place only one per time.
        Also there need walls that simulate lava movement in caves. Lava is causing 100ms spikes under normal conditions when chunks are loaded.
        For reference, 8.3ms = 120 fps, 16.7ms = 60 fps, 33.3ms = 30 fps.
