My Pipotchi turned 6 last night, and so today all day it was 6. I checked the door icon this morning, no date place. Checked again before Pipotchi went to sleep. No date place. I know the marrying age is 6, but do you have to wait until the tama actually turns 7 until the date place unlocks or something? I guess tomorrow I'll find out, but just wanted to check to see if anyone had this problem or knew why it happened.
