Leveling up Twice
I leveled up in Spanish to level 20, but it sent me the message twice and gave me 40 Lingots instead of 20. It also is showing that I am still level 19 when I comment on things.
Sometimes I find that logging out and back in again resets it all correctly. I don't know if it would help with this, but it's worth a try.
Are you sure it gave you the lingots twice?
You will often find after a level change that it shows in some views and not others for a little while. And the levels alongside your name are unreliable, there's a weird glitch that can send them all over the place at times.
Seriously. The levels beside my little flag circles are wrong 95% of the time. In fact, when they're accurate, I'm surprised.
Yea, I'm sure it gave me the Lingots twice, unless someone gave me the 20 Lingots at the same time.
Quod erat demonstrandum - as demonstrated. The Spanish level next to my name changed three times in the course of the thread.
I decided I would make a post of all the courses (languages) you can learn on Duolingo, and provide links to all of them. Here it goes:
