Pretty much what Slash said. If a mistake has been made, then you must inform Pokemaster or a member of staff via:
- You may sometimes find PM or other staff in our chat room.
- Make a post here on meta as you have done. But try not to make loads and loads of them.
- There are threads for contributions and corrections. Please check them out.
Talk to someone by these and inform them of your problems.
However, for your example, it isn't actually a mistake. Both of the parent pokemon here can learn Swords Dance naturally or with TM. So when 2 pokemon that can learn a move anyway breed, the resulting egg will have that move. It was useless Gen 4 backwards, as you could pass TMs without using the TM itself. However because of the mechanics on Gen 5 it's rather redundant. Either way they aren't actually egg moves. Rather Premature moves, if you will.
