Some of the technologies, specifically those with formula based costs, such as mining productivity and infinite research, are unaffected by the price multiplier from game setup.

Also, the technology difficulty setting, normal or expensive, doesn't seem to do anything. Am I missing something, or did you decide to pass on that in favor of the simple price multiplier?

I don't know if this one is a bug or intended, but some technologies have an extra multiplier for science beakers in the cost. For instance automation 2 requires 40 red beakers * 2, and high ranks of stack inserter bonus has such multipliers on science packs 1, 2 and 3. But if it is intended, why only those? I couldn't find any other that did it, but it would not be such a bad idea if techs required more of the cheap science packs, compared to the expensive ones. The red and green beakers are so cheap in the late game.

Thanks for the report,

Some technologies deliberately have some packs required more than others, such as railway.

The price modifier only affects the count of these packs required, the 'x10' at the end

I am not sure you got the main problem I was referring to, or maybe I shouldn't have brought up two issues in one post. The main bug I reported was that some techs have the same cost, regardless of the price multiplier. For instance Mining Productivity 1 costs 100 each of red and green science, regardless of the multiplier. All infinite techs are unaffected by the price multiplier as well. You don't seem to apply it to techs whose cost is determined by formula.

The issue with the extra multiplier on some of the packs, such as automation 2 and railway was a separate thing. Also, you didn't respond to the question about tech difficulty setting, normal or expensive, there doesn't seem to be any difference between those two.

Right, sorry about that

At the moment the expensive and normal technology difficulties are the same, we haven't had time to work on the new settings

And i can confirm that the price multiplier isn't working for infinite technologies

For what it is worth, in the mod I am busy updating I managed to get this working for the formulas by simply wrapping the formula.
Where the prefix is something like "2*(" and the postfix is something like")"
I.e. simply take the formula and just multiply by 2 (or whatever the factor is).

I would also think that few techs - the real basics like automation and logistics - could be maybe exepmted from multiplier.
Crafting 100's of red science by hand might not be the most fun experience... and you might need them to get assembler.

Thanks for the report, it is fixed for the next version.
