When we pick a new power (improvement, talents...) a confirmation window pops asking if you are sure.
However, you are not asked when you click 'Undo' at the Retcon window. Sometimes I click on it by mistake, or I click twice on it, and I waste lots of resources.
Please, add a confirmation window when you click on 'UNDO'.

I have never actually clicked it too many times, but I almost have and I realize how easy it could be to do it.
