I wonder...

[TestDummy]

Hello, when a wonder is built, can I sell the items it gives me for free?

Like after building Sun Tzu's Art of War, can I sell all my Barracks without losing the benefit of the wonder (since it gives a Barrack everywhere)?

Thanks.

Certainly works with Granaries and the Pyramids .. not tried it with Barracks + Sun Tzu's .. but imagine you can ..

You will know as it will let you sell it, yet the Barracks will remain in your built list in the city view!!! Its actually a real pain, as its not easy to remember where you build the damn things ..

You can sell a granary that was in your city before the Pyramids were built. You can sell a barracks that was in your city before Sun Tzu's Art of War was built. You can sell these at any time, even after the wonders are built.

You cannot sell the freebies.
