1. When learning vocab -> sentences -> going to next page of sentences opens a new dialog instead of replacing the current dialog. So for each page, you'd have to press an X to close it.
2. Sentence sort is not consistent. I was looking at sentences for わけにはいかない which has 90 sentences. I paged through the whole thing and when looking at bug (1), I noticed that if I opened the next page twice (it would open 2 dialogs), sometimes the sentences would be in a different order. So I copied all 90 sentences, and only got 81 unique sentences. Then I reloaded page 9 and found a sentence that didn't appear on the first run through. So my conclusion is the sort is not consistent.
Maybe easier to see on 有り金/ありがね which has 19 sentences (actually only 18?). I copied all the sentences twice, and I got 15 unique sentences the first time, then 17 unique sentences the second time.
3. Sentence counts sometimes wrong. See 19 vs 18 above. Also spotted on other words, like 寄り/より which says there are 2 sentences but there's only 1.
#1 is fixed, thanks! #3 is also fixed, but as we are working through a large number of improvements to the sentences thanks to the work of a native speaker who is helping out, the numbers will sometimes be in flux, but will fix themselves.
As to #2 - it should also be fixed. It was a bit of an interesting one getting caused by a non-deterministic ordering of rows coming out of mysql due to the other order commands already in the query.
