"Strengthen Skills" always gives me same lesson

[slammy83]

Most of my Spanish tree is gold, with about 8 or 10 lessons needing review to get back to gold. BUT no matter how many times I practice using "Strengthen Skills," I always get the same lesson (using "ir future," which already happens to be gold). Can this be fixed??? Up until now, Duo always gave me a lesson that needed to be reviewed.

This is most likely a bug, and we are working on a fix right now for this as we learn more. Thanks for reporting! =]

• If you used the "General strengthen button" then try the "Skill strengthening button"

• or try my favourite method

This is suddenly happening to me with Esperanto's "Expressions" lesson. I thought it was bizarre because there were about 7 skills higher in the tree that needed practice, and normally the topmost non-gold skill is what gets strengthened. Now nothing is getting strengthened, it's just the same sentences over and over unless I strengthen in a specific skill.

It happens on both web and iOS. Here's another thread about the same thing: https://www.duolingo.com/comment/26004137

Yeah. I'll upvote this thread to increase the chance of occurrence of the bug being noticed by the programmers, hopefully they'll find a way to remove it once it's recognized.
