Too much time! I had 23181493.21 Seconds instead of 30 seconds!!
The time shown on the timer was 23181493.21 seconds instead of the normal 30 seconds - this clearly is a malfunction. I have had something similar to this before!
Just for clarity's sake: this is a global Duolingo issue which we can't do anything about.
When you're experiencing this issue, it's better to report it in the global troubleshooting discussion. For as far as I'm aware, however, there is no solution to this glitch. ^^"
