Xavion covered basically everything here, including the horrible water problems when trying to including non-BR turbines in a closed loop.I was trying to find an Oblivion Hive. They used to be easy to find in certain biomes, but I can't find any. Have I been extremely unlucky or have their spawn conditions changed? Also, I checked the Gendustry machines and I'm missing the Advanced Mutatron. I can see no script entry that may have disabled it so I'm wondering what happened.
One more thing: I was checking Big Reactors. Since the reactor power tap is disabled, I can't run a passive reactor to get the cyanite in order to make a turbine, and the only cyanite recipe I can see is a 5% chance when sending yellorite ore through the SAG mill. Is that correct or have I overlooked something?
The only thing I'll add is that you can get a better return on the SAG mill by using Dark Steel grinding balls. I hoard all the dark steel items/ingots I find in chests for precisely this reason.
So far I've played two games where I was able to grind all the cyanite I need straight up from the random yellorite and dark steel I've found. I've never wasted power.
