Oh yeah, that's a little annoying lol.I'm using EonTimer. The parents I deposited were x/x/x/31/31/x (A) and x/x/x/x/31/31 (B), so the closest flawless special spread that works for them is on frame 28284, which is over 7 minutes further than the one I was aiming for on standard spreads (frame 2391).
I'm doing it on a cart. Thanks though!
It might take a while, but you could also breed a x/x/A/A/A/A parent and a x/x/x/x/B/B parent. You can try different spreads this way. The closest spread for alternate would be 9506, but it's much better than 28284. Like, if, after replacing the parents and getting an egg again, you're still not hitting standards spread, try switching to alternate, which is close to 3 minutes.
