How do we get the 3x3 building? Have completed the event. No 3x3 building! ((Are the reward buildings the same as they were in beta? Two 2x2 buildings and one 3x3 that have to be touching each other to get maximum bonus? It's a bit of an odd configuration. Also, as was said in beta, is city defence one of the bonuses for having all 3 touching? Not that great a reward in my opinion.
