We are still trying to dissect all of the tiny little details hidden in the background during My Little Pony: A New Generation, but one big standout one that was recently confirmed by movie artist Imalou over on Twitter is too good to pass up! Apparently the Tree of Harmony is still there, just without it's buildings in G4. The timeline here must be huge if basically all of that nice architecture is gone. It will be interesting to see how it all plays out once we get the series, and hopefully start tackling some of these multi-generation changes Equestria has experienced.

Thanks to Miak for the heads up!
