Are bonus skills supposed to disappear?
I purchased the 'Flirting' bonus skill for French from the store, then completed the first lesson from it. Without exiting the skill, but after finishing the lesson, I went to the 'Words' page. The words I should have had from the lesson did not appear, but 'Review you flashcards' still tested them.
I clicked 'Home', to find that the skill had been removed from my tree, and the lingots were refunded. However, my XP had not changed.
I then repurchased the skill, and completed the other two lessons from it (the first lesson was still marked as done).
Going, once again, to the 'Words' page, I had the same issue (words not there); so I went back to the 'Home' page, and found the skill to have disappeared again. However, this time without refund.
What's going on? Should I send a bug report?
EDIT: It reappeared in the tree (when I reloaded the page a few times), so that's solved; but I still don't have words from it.
Hmmm... maybe bonus skills don't add words to the word page? It's really to teach you phrases and not individual words, so maybe that's why.
I thought that too, but I'm not too sure because:
Firstly: I found the words it teaches quite useful, and can't think why it'd not add it; and secondly: It still tests me on those words.
I'd guess either an A/B test or a glitch. If you really want to memorize words, though, I recommend using a program like memrise or tinycards or quizlet.
