I'm pretty sure that I've seen this question asked, and the answer is always no, but is there something going on with the breeding mechanics after the most recent update (Y version)? I am breeding a female 31/31/X/31/31/31 Shroomish (holding an ever stone) with a 31/31/31/31/31/31 Ditto (holding Destiny Knot) and am getting the exact same results every batch. 31/31/X/31/31/31 (obviously straight from the shroomish), X/31/31/31/31/31, 31/31/X/31/X/31, or 31/31/31/31/31/X - those are the only spreads that show up. I've been at it over a couple of play sessions (3 different days), and only recently noticed the trend. During my session today I bred ~50 eggs, and the same amount the other night (same four spreads both times). Nothing is hacked; I don't use or even have Power Saves and the Ditto has been used for every other breed I've done in Y. No idea what's going on. An interesting thing to note is that on day 1 I did get a 6 IV male, but kept going for a female. The only thing I don't remember is whether the first session was pre-update.
EDIT: batch = 5 eggs, if that wasn't obvious.
