I just completed the card deck for “Harvest Hardware” but I wasn’t able to receive the bonus rewards. I opened the card deck and it had the “new” notification on the latest sticker I just received ...

When you complete the sticker book you don't get the rewards it mentions which is a huge amount, it just takes you to the next sticker book. What's the point.

I didn't receive a new building (like a silo or doghouse) after completing the sticker book?

I completed the sticker album and when I opened the chest I didn't get a new building, can I please get my new building

I completed the sticker event and received the reward chest, but opened it to find no buildings inside. Is that normal?
