Because i am talentless bird they look like regular spitter repainted to copper color, but these are copper biters, and Their nests generate only on water.
If you have too much of a problem with them then there could be 2 things happening:
You are probably generating too much pollution.
Let me explain:
Pollution on pelagos are EM waves. They are generated by all electrical devices and generators.
But Biochambers, Diesel machines, Calciner, and burners don't generate pollution here at all because of that fact, and planet is balanced around them.
I should make tips and tricks for pollution, it is unique in how it works
Diesel machines generally don't also require copper so except for things like science lab, and oil rigs, it is possible to build a base that almost don't generate pollution at all.
I messed up the numbers a bit.
But as far as testing goes soo far you are one of the first people reporting this issue
If you don't fight the planet it should not fight back, similar to how you can beat gleba without defending plantations if you keep spore cloud at the same size.
I Agree that it is brutal if you play as usuall, but is should be fine if you look at pollution cloud from time to time and focus on burner into diesel tech
Fuel leech is helpfull
If you feel some diesel machine is missing (some machine that could be usefull) then let me know
