My Skritter is acting up tonight, had Skritter freeze up, so I clicked practice again to reload it and did another character and it froze again. Now I have characters immediately reappearing in the same order, I think its 衬衫,糟糕,颜色,暖和, I've done this sequence at least 4-5 times, getting it right every single time. Then they will pop back up a minute later saying still learning. I hope by hitting practice it'll fix the problem but wanted to inform you
