I'm not sure what the actual problem is, but there are a handful of other mod-added Shortcuts that seem to toggle this mod's option to show the tower radius when clicked, such as the Add Toolbar or Toggle Toolbars buttons from Toolbars, among others.

Thanks for reporting, found the issue, will release an update soon.

Checking in on this; any news on a fix? Thanks.

I had other changes in progress and wanted to do them before releasing, but they'll take more time, so i released the fix in 0.1.3
