I saw it, too, after the latest update, but I wasn't really sure like "There were sicks slots for level packs before, weren't there???" But now they are only four. I'm glad year 2 will be released completely, yet sad. So much still to come, but according to the article they are not really working on year 3 anymore.
Well, the server crashed, they tried to upload it to another server, but it's still not working.
"Best Day Ever!!!"
