When holding shift, the tooltip of the defense you're inspecting becomes that of the one you BUILD last.
Only works when the build defense isn't sold already. Repro Chance: 100% Steps for Bug Repro:
Go to Private Tavern/Town HUB/Any Map.
place down 2 defenses (or more).
inspect any defense (that is not the last one build).
press (and hold) shift. See the tooltip change.
Done.
Expected Results: I expect that the tooltip doesn't change.
