Duolingo just told me I completed the French tree. I am level 3.
I have completed the German and Italian trees but I just started learning French yesterday. After I completed ''phrases'' it notified me that I ''conquered the French skill tree'' instead of ''you successfully completed phrases'' (or whatever it should say at the end of chapter). I clicked ok and I landed on my Italian tree and the French one still looks incomplete (like it should be). I guess it just have me the wrong notification.
I reported this some time ago and got this mail (May 30) - didn't bother following the instructions though, because the bug is so cute I don't mind getting it. Got it again once in Italian, again on the laptop and I know something is off with my Flash there.
Happy to help. There are a few reasons why this might be happening. It’s possible that you have an outdated version of Flash installed, you installed browser extensions that block Flash (i.e. Flashblock), or that Flash crashed.
Here’s what I suggest you do:
Try reloading the page in your browser.
Try quitting and restarting your browser.
If 1 and 2 don’t do the trick, update Flash Here’s a helpful link to get you on your way: http://www.adobe.com/go/EN_US-H-GET-FLASH
