It's more appearing offy than vanishing loo, no matter how far back you go it's still toilets. Wonder what happened.
I did think at first that maybe the pics of the loo were taken when driving straight down lodge lane, and that they didn't get back to driving across it and down Beaumont Street until a while later, and hence the offy only appears when actually "stood" on the cross-road (i.e. they used the later picture). However, I've since tried looking from the end of Beaumont Street on the map and its back to a loo, so it is only that exact position that the offy appears.
I'm now convinced however that the offy management just didn't fully think through the idea of having a hologram for their signage.
