Tower can be clicked (to toggle the range display), even when hidden by other windows.

And I was wondering how that option was turning off...

Wait, you mean you can click through a different window?

[noble merlin]

Yeah, I was able to click the Tower through Statistics and Options.

Oh, I think I saw this like a year ago? Might have shoved it somewhere in #infinity-phase

Now that I know how unity does things, I think it's just a raycast staying active?

You mean a raycast not being blocked by the UI^^
(In unity you can save performance by disabling raycast checks for ui components that do not need interference with player input like images without a tooltip and other decorational stuff)
