@bshag4lv No. You can find them by either typing in the name of the treat in the search bar or by clicking the drop-down menu on the right-hand side of the b/b screen (just above the items) clicking on "packs" then clicking on "cottage living"; that will show you just about all the b/b items in the cottage living pack.
If your sim gave her llama a treat but she can't make it (when she *should* be able to) it could be mod related. First, I'd remove your mods folder to your desktop then go in the game to see if it still happens. If your sim can now make the treats that you're sure she knows then it's most likely a mod issue. Then, if you downloaded any mods recently (say within last month) I'd try removing those then going back in the game. If she still can't make them then you'll need to do a 50/50 check of your mods. You can also try repairing the game to see if that fixes it (I'm sure you already know all this, but it never hurts to have a reminder just in case :)). You can also check AnswersHQ to see if anyone else reported the same issue. If they did you can click the "me too" button.
