Science and Tech tree order

[Albrat]

I would like to suggest that all Science that requires the Science tech Pack 3 be made un-available untill you have researched "battery" tech. This is due to the fact that you can not produce the Tech 3 science untill you have battery tech. So I can currently queue advanced Oil Processing as my next tech but can not produce tech 3 science yet to do the research...

I was also wondering why this dependency was overlooked

So it shows you recipes you can't research because you can't make the research materials?

I don't think this is too bad of a thing, but I agree it should be fixed. Until recently you could research some things you couldn't build yet, because you hadn't researched how to make all the parts.
