We're excited to announce that we've fully migrated the Xbox Forums to their new home, here on the Microsoft Community forums!
As of today, going to forums.xbox.com will redirect you here to the Xbox area of the Community forums. We've moved all of your existing threads over so you can continue and start conversations with the new forums experience.
We sincerely appreciate the feedback you have provided over this transition and can't wait for you to check out the new Xbox Forums!
Yes, I made sure I researched everything. I started a new challange mode zoo to try it again but I'm afraid I'll run into the same problem and have it be for nothing. There is too much of the blue bar missing in the achievements for it to just be a few things.
I guess some things didn't register for some reason.
I just unlocked the achievement. Somehow I was missing the scenery items. One of three things happened. Either I overlooked them somehow (which I know I didn't), they appeared to be researched already or they didn't register the first time.
