Skill dependencies on updated tree
I notice with the updated tree I now have 3 or 4 levels of skills opening up that don't meet the stated dependencies. This is not big deal but it does make it a little harder for me to keep track of which skill I am working on.
Does refreshing learnt skills often make it more likely to get the words from untouched skills (grey boxes)? I've been getting a lot of new words lately that I haven't seen before and I know they are from lessons further on in the tree.. eg. when I was trying to get to the second lock, I was getting a lot of sentences with está/están/etc, which was confusing at first because I hadn't done the lessons.. I was and still am also getting a lot of sentences with this/that/those (from a skill that's still grey)..
Last weekend, after refreshing all the skills I'd learnt, I had 8 new colored skills past the second lock (though I hadn't unlock this section/didn't have a tick). Then they turned grey during the week, but I was getting loads of new words (I think from these lessons). Now they're colored again.. is this normal?
