Civilization – Does Changing Production Transfer Hammers

civilization-5

Civilization V is really kicking me hard this time around. Was an old-pro at Civ IV but this one's a completely different beast.

Anyway, back in Civ IV, when you changed production on a unit/building/wonder, you would keep some of those hammers, letting them transfer over to your new project. Great when you were beat to a wonder. However, with Civ V, it doesn't appear to be the case. Do hammers transfer at all if you change production?

Mostly concerned about wonders as I have a tendency to pick the wrong ones. And does anyone know of a mod that might fix this?

When you are beaten to a wonder by another player/AI, you get some form of recompense in money - in face, you get more gold than if the produced hammers had been put into 'producing' gold in the city.

When you switch construction between buildings, the expended hammers hang on in production of the initial building so it retains progress if you continue building it. If for example, you're building a settler, but suddenly realise you need a warrior or you're doomed, you can switch to produce the warrior then switch back to the settler, and the settler will still be part-way through construction.

As for @rikitikitik's comment, I can neither confirm or deny whether there is any degradation of hammers over time.
