I am not aware of any change regarding this, but I also haven't played this game in a year or so (only loosely followed the patchnotes), so things might have change (though I doubt it).

Is this still an issue? I know there's been a few updates, any of them address this?

Like the author said makes sense that bronze is weaker then iron game wise because its unlocked sooner and for everything else later unlocks are better.

If you want to go for history though these are what are considered the technology ages, notice iron is after bronze.
3.3 million years ago to 2500 BC: Stone Age.
2500 to 2300 BC: Chalcolithic Age.
2300 to 700 BC: Bronze Age.
700 to 450 BC: Iron Age.
450 BC to 450 AD: Classical Age.
450 to 1400 AD: Middle Ages.
1400 to 1750 AD: Renaissance.
1750 to 1950 AD: Industrial Age.

''The first method for refining iron was the bloomery furnace. A bloomery furnace doesn’t completely melt iron. What you get out are a bunch of nuggets (blooms) which are full of slag and are of variable quality. Some of the blooms are almost pure iron, but some randomly come out with the right amount of carbon to be halfway-decent steel. Steel is an alloy of iron and carbon, and the proportions have to be exactly right — too much carbon and the metal is too brittle and too little and it’s soft as butter. It took the better part of a thousand years after the bronze age collapse for smiths to work out how to reliably make steel blades that were as good as bronze.''

Historically speaking tho we where bronze working before we where able to work iron efficiently and while bronze was strong it was still weaker then iron

@Darth Porgus
bronze is softer making it less effective as a tool than iron

@Trishirt
No, it doesn't.

Does this mod Disable Achievements?

@Darth Porgus
The Problem is that it doesn't make sense from a Gameplay standpoint. You will get Bronze Tools much earlier than Iron Tools.
Like, I have Bronze Tools now for 2 days in my playthrough (2 RL days) and still no Iron Age. Yes, I could rush to it, but still, you unlock Bronze Tools before. Therefore, Bronze Tools should be worse than Iron Tools.

It is a game after all, not a "historical reality simulator".

And hey, if you think it's fine the way it is, then simply don't get the mod.

Pewter is also an alloy, but it can be bent by hand and melted on a stove. Alloying doesn't just make metals stronger. Bronze is quite ductile which means it is easy to work, but also deforms more easily in use. Iron is harder and more dense than bronze. Iron broadly supplanted bronze historically because it was easier and cheaper to produce and had similar or better properties for making tools and weapons.

Bronze is stronger than iron because it is an alloy of two other metals, making it denser and difficult to break with less friction.
It does make sense, historically.

ive noticed this too, thank you for this fix! it always confused me because i could ignore a key point of the game and production chain

nice it is backwards.
