HG/SS Egg Trades Lose Shininess?

Something really, really weird just happened.

My friend got a shiny Ralts egg, but she saved before it hatched so she reset and gave it to me via the Union Room. I was totally stoked because shiny Gardevoir looks awesome.

When it hatched on my game, it was apparently still shiny, so I gave it an EXP share and killed some stuff (LT Surge's gym :D ). It evolved into a very un-shiny Kirlia.

What gives? Anyone else have this happen to them? Pokemon should not loose shininess!
Though to be fair, I'm not sure the evolution did it. I put it in front of my party a little before that, and it looked green to me on the map. I figured it was a graphical oversight on GameFreak's part. Maybe putting it in the lead slot messed it up?

Regardless, it really bites.
 
Pretty sure it would be considered legit.
She RNG'd it, but it wasn't Action Replay'd.
 
It's happened to people before, trading legit shiny Eggs from D/P/P to HG/SS and then them losing shiniess when or after they hatch.

There is no way to get the shiny-ness back, I'm afraid.

I figured that there would be no way to undo it, but I feel a little better knowing other people are suffering with me. :D

Any technical reason for this?

I'd like to know this as well. Thankfully, my Ninetails stayed shiny!!!1

Nope. I just read a few days ago that a few people on forums like Serebii have encountered this problem, I don't actually know anything technical about it.

Someone on Serebii mentioned it might be to do with the Secret ID or something, but I really don't know, as the inner mechanics of the game right now are beyond me.

I see. Well, thanks for the heads-up.

My theory is that it may be putting it in your lead position, since that seems to be what broke it for me.
 
When RNGing, you're making the Pokémon in the egg to have a certain personality value. This value, the trainer ID and the trainer SID combined determine whether the Pokémon is shiny or not. That is, the shiny egg is made for certain ID numbers.

When you trade the egg to another game, it keeps the IDs of the original trainer. However, when you hatch the egg in another game, it overwrites those IDs with yours. And, because of this, that specific personality value doesn't trigger the shininess anymore.

The Pokémon that hatches appears to be shiny because the IDs are replaced and the shininess rechecked only after you exit the hatching screen. (It will be non-shiny right from the beginning.)

If you RNGed a shiny egg in any game and traded it to any other game before hatching it, the exact same would happen, except if the games shared both the trainer ID and SID, so this is nothing new really.

Alrighty, that makes sense. Thank you.

Though, we did this with a Vulpix and it's still shiny, 50 levels and a Fire Stone later. It was from the same two games. Guess we just got lucky.

Hopefully that's the end of it, then, unless we start hearing from people with lost shinyness not dealing with egg trades. Thanks again for the speedy explanation!
 
What about IV's, Natures, secret IDs etc?

IVs, nature, gender and ability should be based solely on the personality value, so they shouldn't change. Secret ID (to which I referred before as SID) assigned with the Pokémon does change to whatever the hatcher trainer's is, because it isn't Pokémon-specific but instead Original Trainer specific.

Captain Obvious here. So if we already hatch the egg in DPPt, then trade it to HGSS, would that pokemon lose the shiny goodness when it evolves?

The Pokémon will retain its shininess only if it's hatched in the same game chip it was collected in.

Evolution has no effect on anything - as I stated already there, the shininess of traded egg Pokémon is gone right after the hatching screen.

It appears so. this seems like a major flaw.

From what I understand about this glitch, it only affects eggs that are produced on a DPP game and hatched on HG/SS. If a pokemon was already hatched, and was shiny, the pokemon can be traded safely.

Precisely, because in that case, the ID assigned to the Pokémon does not change. It's only when the ID changes that this apparently happens.

(I wonder if anyone can check if this happens within DPPt games - it may just only have been noticed now because there's a lot of trading going on between old established files and newer files.)
