I’ve uploaded some hacks to make recognition better for problem strokes. The “walk” radical 辶 (in 这, for example) was being difficult. It should be very accepting, now. Let us know what other strokes are still gumming things up for you.
I also reuploaded all the strokes at 3:00 am this morning, so you should see a lot of the stroke order fixes you all have been reporting finally take effect, including the ability to write slanted 女 radicals (like in 好) with the horizontal stroke last.
There was a bug with the vocabulary list addition tonight, which has been fixed. There may also be another that hasn’t; let us know if you are having troubles adding lists, and tell us which browser you’re on. Thanks!
