Yeah I assumed the bathrooms needed to be far away from the tents (who'd want to sleep next to that smell?) and I didn't consider right-clicking the buildings at all. It's best if players can learn your controls/mechanics intuitively rather than relying on menus or reading instructions.
Also, nothing happens if you left-click the buildings, correct? So right-clicking might be necessary. I think stats would be better in a popup tooltip when you hover without clicking, and then clicking could bring up an upgrade menu.
