Is there a bug with the Ukrainian skill strengths?
I've been working through the Ukrainian course for about a week, and not once have I had to review anything - the skill levels have all stayed gold, even if I haven't practised them for a day. This seems unusual because I've had multiple levels to review in all of my other languages, and I've even had to review tested-out or completed skills, with no mistakes, the very next day.
Admittedly I don't really know how the calculations are made for refreshing skills, and I have been practising existing Ukrainian skills more than other languages (because I find the vocabulary harder to learn), but I still think it's odd all my skill levels have stayed at the same "gold" strength.
Does anyone else have this problem of non-deteriorating Ukrainian skills? Or, is it just a sign that I'm practising a lot? :P
