As the title so the message, Frostline Omnivore, while it works wonder for normal Strip Miners, it doesnt affect the cycle time of Modulated Strip miner. Is it intended or is it a bug?
The cycle time of the Frostline Omnivore only works with Ice, while the yield amount bonus applies only to Ore. So, yes it is intended.
Actually it applies on Strip Miner I aswell.
Sim it and you will see for yourself.
