I see!

Thanks for trying to help. I contacted a few times with my internet provider and they couldn't find any issue... which I actually believe, because the internet works just fine on my computer and the phone, it's only the 3ds that randomly decides to be glitchy when trying to play ACNL. Even when I run a connection checkup on it, it comes out clean! It's a weird thing...
Anyway, I'm glad it didn't actually take that long to be able to visit you. I hope you enjoy the items as well as the little surprises!
