BTW, there should be 2 major warnings to all new factorio players
1) Non-forrest based factories are for advanced players only
2) Be fucking faceful when boosting your base.
Oh, naive me thought, that nothing will happen, if I re-work the base imputs and smelters slightly, but instead, I did get such a huge jump in the polution, that I had to spend 10 hours re-building the base defences while under a constant attacks.
There is nothing geadlier, then when an idle factory starts working.
