The tech tree changes have reintroduced some of the economy problems.
Mines now give +1 production, +1 production with gunpowder, +1 production with steam power.
Lumbermills are available at engineering, give +1 production, give an extra +1 production with machinery, +1 production with Steam POwer.
Villages give +1 gold +1 science, +1 gold on fresh water with sailing, +1 gold on non-fresh water with economics
Farms give +1food, +1 food with fresh water with civil service, +1 food on non-fresh water with fertilizer.
So we no longer have a situation where improvements are roughly equal on fresh water; it is a no-brainer to build villages or farms on river-adjacent tiles, there is no longer a reason to build lumbermills or mines there.
So in the early game, a fresh water village will give +2 gold and +1 science, while a fresh water mine will give +1 production.
This doesn't make sense to me.
