Awesome!! Thanks for confirming and the awesome feedback. Honestly, that was the design debate I had.
I had a few options, one was how it is now, another is always unselecting after each placement, or the one you suggested. And i feel like I agree with the third option. Based on how people seem to naturally try play. So i appreciate the feedback!! when I implement shortcut keys, Ill rework it so it keeps the selected one selected when you get enough money. ^.^
