Tunnels can be built on objects

Tunnels can be built on sources/minerals/controllers (I'd assume keeper lairs as well)
Not sure if this is intended or not.
This is not intended, thank you for your report, we'll take a look.
Actually, on the second thought, it's nothing wrong about being able to build tunnels under these objects (because you can't actually walk there). This is the same as that you can build a road under a non-walkable structure.
