Breeding bug

When breeding without Ditto, all hatched eggs are female. This makes it impossible to obtain certain egg moves.

Same issue happens to me. I was trying to get Rock Blast Heracross, breeding Shuckle Male and a female Heracross. Only hatched female Heracross (although with Rock Blast)

After doing some more testing, this bug seems to happen whenever a female Pokemon is used, even with Ditto. The only way to get a non female egg is from Ditto + a Male Pokemon, making cross breeding egg moves impossible.

Confirming the above observations. Breeding only works properly with male + ditto.

Addendum: Nidoking and Nidoqueen do produce male and female eggs.

Although, the ratio doesn't seem to be 50/50 (made 48 eggs; 35 male, 13 female), despite 50 percent being listed in daycare.asm under the .GotMother script for nidoran breeding.

Breeding Ursaluna also seems to work the same way as the Nidos (it has the same 9bit species value as Nidoran_F).

Another potential bug, bot sure if it should be here or opened as something else: I accidentally told the grandpa I didn't want the egg while testing this and could not get him to generate another egg (despite having max attraction of the mons in the daycare) until I took one of them out of the daycare and put it back in. Restarting the emulator and even closing it after saving didn't fix it either. I attempted for over ten minutes. After taking out and putting a mon back in the daycare eggs starting generating almost immediately.

Just to address this, this has a 0.06% chance of occurring. Very unlikely, but not outside the realm of human possibility. I didn't change anything with the Nido code but on my own run after pushing the fix to the gender issue, I made 26 eggs and got 14 male and 12 female, which is essentially 50/50. Unless someone else raises this issue, I'm satisfied to say this isn't bugged.
