What's up with a second form of Rockruff and the third form of Greninja in Pokémon HOME? I almost completed the Pokédex but the mobile version still wants those entries. I got Ash-Greninja but there is a third form? I also have the problem that I don't have all ten forms of Furfrou registered and that's both on the Switch and on mobile.
For Rockruff, that most likely refers to one with Own Tempo, the only kind that can evolve into Dusk Forme Lycanroc. My guess is that the easiest thing to do with Rockruff to allow it a fourth Ability and an alternate exclusive form, as far as programming goes, is to give it a second variant.
As for Greninja, your guess is as good as mine.
Someone's been datamining Pokemon HOME and they found some interesting information for our friend here Regigigas lol. Apparently he now has access to Protect and Rest lol. With Galarian Weezing coming in, if Regigigas ever comes out in the future, he could live up to his Creation Trio-throwing strength lol.
And Aurorus is STILL denied Power Gem despite having gems embedded in its sides. Just you watch--they're not going to add Aurora Veil to its level-up moves either.
Heard about this on the 12th via both Discord and Twitter. Hoping that Game Freak and Nintendo patch it asap. It sucks when some people ruin things for others.
You'll have to prepare for the worst, that there will be no patches at all. To my knowledge, there's only ever been one case of them patching something via an update instead of saving it the following game, which was the save glitch in Lumiose in
X and Y. People have used Wonder Trades to cause trouble almost as soon as it began, and neither Game Freak nor The Pokémon Company have ever made a direct response.
That being said, it might be different this time, as this is the first generation to have extensive post-release updates.
