I know a week or so ago I posted about the old practice page way over repeating new words that were marked wrong the first time. I have been using the new practice page to overcome this, but now I seem to be see the opposite effect. Characters I am fairly sure I got wrong the first time (usually red and occasionally marked yellow by me) don't appear again for hours, and even if I get them wrong a second time it is hours later and they only appear with maybe 125% or so (give or take).

A completely separate bug, but also quite weird/serious, is with the custom lists. At first I just thought I was crazy, but now I am sure that it has happened several times. I will save a list (or edits to a list), activate it, etc. Then when I go back to edit it again, several of the latest words added will have disappeared. This has happened even after the words have been added from the list into my studying on the practice page. I'm not sure how this happens, and since most of my lists i make on my iphone dictionary app first I can easily re-add them, but obviously it is not a good situation :)

I too am experiencing the custom-list bug.

Are the characters you got wrong part of words? I'm noticing a bug in that situation... Especially after the word appears for the first time.

Could you give an example of a word that's done what you describe, Hobbes? Then I can look up the history of it and figure out what's going on.

As for the custom list bug, I'll look into it soon! I have an idea what may be causing it...

ok here goes (sorry no IME on this computer)...

words I've gotten wrong 2-3 times in a row (i think)
xiao tan
ce suan
yan su

words I possibly missed only 1-2 times in a row
gai ge
xia zai

a word that was weirdly scheduled but i just got it right.
liu lan qi

I think there are at least a few more. Further confirmation is that when I went to study today, almost all the words that started to pop up I couldn't remember at all. (recently added but not practiced hardly at all).

Hope that helps!

In all these cases, you never submitted them as red, at least that's what it says in the backend. You submitted them as yellow, which schedules differently. It's still considered 'wrong' but not as much. I'll tweak it so that it's a little lower when you score it as yellow, but if you're not seeing it enough, score it as red.

In relation to the old practice system, red = wrong, green = right, and yellow is somewhere in between.

Do you think that explains it?

well, I initially thought maybe it was because on some I was marking them as yellow the first time (like you said, maybe I expected this to be a lower interval than I thought).

But out of those words I listed, there are some I am almost sure I marked as red from the beginning, and I am completely sure I have marked them as red since then. So if it still says I have never marked them completely wrong, something is definitely up.

Unless like Byzanti said, it happens within words where I got the other character right or maybe marked as yellow from the first time, and that somehow causes the error on the other character to not be picked up?

also I hope you understand what I was trying to say in that horribly formulated parenthetical statement in the first sentence.

Looks like what happened was you marked the character you got wrong red, but the word ended up being yellow because you got the other character right. Nick says he's changing it so that if one character in a two character word is marked as red, the whole word is scored as red.

Found the custom list bug. I'm not sure what I was thinking when I wrote that code... Anyways, the fix will go up later today, along with some other things.
