The "ending" event (walkthrough; "Step 7 : Go to church to trigger last event leading to endings") doesn't seem to trigger. Anael is level 4 with affection 100 and obedience 200, and I've visited the church several times since, but nothing happens there except the ordinary dialogue choices (talk, follow me, sex, cancel etc) for Anael. (have been playing and patching, saving and loading since v0.15, so it might be related to that; havent started a completely new game for a long time, and certainly not with v0.20...)
On a side note; the text and graphics dont match for several girls (Utako, Kumiko and Shizuru at least, probably many others) when having anal sex in their sleep; the text (which seems to be the same for most girls...) says you turn them around on their belly, images show them lying on their back.
And when approaching Shizuru in her sleep, there's a text starting with "Even with her husband in the same room..."; obviously a mix-up with Yatsumi's sleep event...
Edit: the ending scene suddenly appeared; Anael surprised me in the girls toilet at school a few days later., saying the spell was ready. The "bad endings" dont seem to be implemented yet (at least not for Rin and Saiko, the two I tested), but as long as there's a "Not implemented yet" message about it, it's no problem...
