I lost coins? I know I can't actually spend them for anything, but they're all the Duolingo Geld I have.
. . . so I started by taking four German lessons or so, stacked up a few gold coins for Thursday in my "weekly progress," and went on to wrestle with a translation I'd been working on a week or so ago. I thought I was making some progress - even smoothed out (or so I though) some of my earlier sentence translations. Then I came back to check my progress (had I done enough to call it a night?) and lo! All but one of my gold coins for the day had disappeared. I reloaded the page - nope, still down to one gold coin. Did I offend? Break the rules?
For what it's worth, when I look at your stream it says you did 10 lessons for 100 points, then translated 5 sentences for 2 points. However, in my stream it only shows you having done 4 lessons for 40 points. I doubt that information does anything other than contribute to the mystery.
Taxes makes sense. Or maybe bandits. I don't know what my total count had been, so I don't know whether I lost anything there. Maybe it's part of the deterioration of skills thing - which I keep imagining as vocabulary vanishing, hard-won conjugations unraveling, my shaky grip on the conditional tense growing still weaker, then falling away . . .
