Im using volcano like energy generator. Aftger magma cool down to igneous rock, robominer makes space for fresh magma.
Upper row have mass over 20 000kgs, but normal lava title can have only about 1800kg.
Mined igneous rock (with temperature under melting point) was changed to new row of material - this causes damage of my robot miner & his cooling
