Newspaper got it wrong?

2 weeks ago the newspaper said that yesterday was going to be the underwater adventure. I went on cp yesterday, nothing had happened. Today, nothing had happened. It's as though they have completely forgotten about the underwater adventure, and replaced it in the next newspaper. In that newspaper there was an advert that on July 26th it all starts. I thought they either got the date wrong for the underwater adventure or they had moved it, because on the advert was somebody surfing! But it turns out that the stamps are coming out that day! That was what the advertisement was for. But now cp say stamp books come out on 27th so I am really confused and I'm just gonna wait to see what happens
