I just wanted to warn you that one can lose an entire DW day if you play with the DS clock settings. The DW website will tell you you can access the dream world, but the game will say your Game Sync is not fully charged, please wait for 1 day. I think Nintendo is attempting to fix this bug, I hope it will.
It doesn't make any sense to me. You need to connect to Wi-Fi to check if your DW device is charged. Then shouldn't it check if the DW website allows you to log in? Nope, it seems it looks at your ingame clock, which is pointless. Blah, I just changed my clock to try the Royal Unova because 10pm is not in the evening for Japanese programmers =,=""".
Just to give a bit of life to this topic, has it happened to you as well?
