Switching a city's production

[Nox Ffred Dragon]

Is there any penalty? Like if I've been building a water mill for a bunch of turns and then I switch to building a Settler.

I recall in some prior Civ games you lost a bunch of the production toward the current item when switching.

Thanks much for any information anyone can offer!

As near as I can tell you lose a small perhaps vanishingly small amounto of production each turn while that is on hold. Now whether that can be countered by keeping it in queue or not I don't know.

You don't lose production by not having something being actively worked on. If you remove an object from the queue, it will remember how much production you put into it.

Thanks!
