Three slots open, only two skills available.
I found this strange when I went to the lingot store. I've bought Flirting and Idioms, and after completing those two I thought I would have unlocked a third one, like holidays.
Anyone having the same problems?
The third one is the Christmas bonus skill and it only shows in the store during that time. Someone posted a work around to get the skill all the time here and I used it myself once upon a time. I don't know if it still works.
Edited to add: The post now says "No longer works" at the top. I didn't notice that earlier.
I also have that problem. I haven't even seen the bonus holiday skill that wstockall mentioned. I feel like duolingo should give us some more bonus lessons to buy in the lingot store. It would be nice to choose some fun lessons to take instead of following the required progression of the language tree and give us some more specific vocabulary to use. Besides, it would just be nice to spend all of these lingots that I have piling up! :)
