That's correct. Nook actually also announced that Residential Services will be unavailable for 1 full day. So I stocked up some extra Miles tickets just in case on the evening before they started to rebuild. Ended up not even using them but messing with my house instead. I can see the temptation to travel in time though. But on the other hand it's also huge part of the experience, it's one big slow grind.
Had my Residential Service building open today. And well, the grind is gonna intensify. Crazy amount of interesting stuff to buy with both miles and bells. Looks like some of the public works projects from New Leaf made it back in a slightly different way of obtaining them. And of course villagers are able to help you pay for bridges and what not again, but I figure it will be like New Leaf. We can be lucky if they donate as much as a few 1000 bells. If even. Kind of hope they fixed that a bit. Anyways, the game opens up big again after having Residential Services upgraded.
Some screens
By the way, I don't really see any of old faces from the New Leaf OT's. But it looks like this thread is quite active, a reason to visit GAF again then.
