Hi.
I'm not sure if it's me messing something up when setting up or adding mods but fluid based techs are unlocked almost immediately.

I noticed that the problem occurred:
-oil extraction(unlock oil processing)
-producing petroleum gas(unlock adv.oil proces.)
-sulfuric acid production(batteries and uranium)
The first tech requiring water extraction works fine.

I'm playing on x10 setting, if that makes any difference.
I will include a link to my save just before the sulfuric acid.

I also tested only with the SpaceAge+Learning mod.
The result is the same.
