Recently Roselia was moved down from RU to the NU tier, there a user make a post about a possible Roselia moveset, that included Spikes and Sleep Powder, but for breeding issues this is impossible, or so we thought.
On PS! I make the moveset with Spikes AND Sleep Powder but PS! din't show any warning message due to the illegal combination. When i typed the /learn command it says that the combination is possible in gen4 and gen5 breeding.
I investigated a little but din't find the pokemon or pokemons to breed or chain breed both move simultaniously on Budew/Roselia.
This lend me to two conclusions:
1- I'm a bad breeder and there is a way to do so, but i couldn't find it, or
2- There is a bug on PS!
I really want to shed some light on the aspect and i want some help to do so.
