Yes im sure and ebony arrows dont have a damage of 30 only 20. and now that i think of it yesterday i did diplomatic imunity and when i reequipted daedric arrows it only increased my bow damage by 24
20+10=30 the overall damage should be 30, instead it was 25+20=45 (ish) as the bows damage increased.
The bug I described was what was patched, not sure what you're experiencing.
Any confirmation of it affecting the Bound Bow?
Yes, before you would get a large boost of bow damage as you're using daedric arrows (i.e. much higher than +24). Now it's fixed.
