I am playing seablock and cant find the fluid burning generators anymore. They do not even show up as disabled or hidden items. It seems like there used to be a bobs power startup setting to enable them, but that is no longer the case. It is not mentioned in the changelog of this mod or seablock.

Yes, the seablock mod pack includes a lot of mods, any of which could theoretically cause this issue. But I would be suprised, if another mod straight up removed the entity and didnt just hide it.

I wouldn't be surprised if they did, it's a surprisingly common thing for them to do.

But, if you were to play with just my mods, they'd be there. Assuming the option for them was enabled, it is by default.
