Glitch: Skills turning gold when they shouldn't.
Sometimes when I click practice, then before starting go back, a skill with four bars turns gold. Also I've had this problem when I've gotten nothing right on a timed practice or lost all hearts on untimed practice.. This needs fixing!
Sometimes I enter practice, do one sentence (which gets marked wrong) and my skills are goldened (whatever, gilded). And I definitely agree, this needs to be fixed! You can't learn anything from answering just one question.
I know this is all based on algorithms, but those need to be revised and fixed, as well.
