Not exactly a game-breaking gltich but just a weird one, since I'll try to select something and 'Louis Bennet' will appear instead. He is, apaprently, invisble and massive to the point that clicking anywhere in the park will select him. I just chose a several-square-meter are to record because that's where I was working at the time.
I can still select groups & items, so it's not exactly game-breaking- or even much of an issue, frankly. It's just kind of bizarre.
