Weird Strengthening Glitch
I was strengthening my Time skill on the Swedish course when I came across this. I got 19 out of 20 answers right and it didn't show up as becoming strengthened in that window. After I clicked out of it it showed it as 5/5 in the lesson view (whatever thats called).
But when I went back to the tree view, it shows up as 4/5 strengthen again. This isn't really a bad glitch, but the lack of everything being gold does bug me more than it probably should.
I'm having this problem just now in Spanish... (although I think it did show up as somewhat strengthened in the end of the lesson, since I'm getting back into the language and hadn't done anything in it for a while) It says 4/5 on the tree, but 5/5 on the lesson page. (perhaps I'll try strengthening again.
