After expanding my boxes on the PC in game (one pokemon in each available box, leave the pokemon center, return to pokemon center and boot PC) a random egg appeared in one of the new boxes. I am not sure if it was there right after expanding the boxes as I did not check them all, I just needed one more so I could do some organizing. I downloaded and installed the v1.1 patch the previous night and my game is a physical cartridge. They are not tradable.
The summary on the egg states:
A mysterious Pokemon Egg that was obtained from the Mystery Zone on 0/0/2000.
The egg watch: Sounds can be heard from inside! This Egg will hatch soon!
Now I know that this egg has appeared after WonderTrades for some people and signals corrupet data. The problem is though I've only done three wonder trades and they were at least a day before this egg appeared. Also the pokemon I recieved from the WonderTrade are still where I left them in the box.
I found one video on youtube documenting a similar experience in Pokemon X and the individual has had the eggs multiply and overwrite the pokemon in the spot they appeared, otherwise I have found very little information regarding this. https://www.youtube.com/watch?v=rkey2Bj_3uo
The only reccomendations I've gotten are to quarentine the Egg/PC box its in and to transfer my pokemon to either another game or PokemonBank and reset my game. I have stopped playing it for the time being but would really like to get back to it as I lost my copy of X and don't have any other gen 6 pokemon games.
What I want help with is:
Can this egg cause futher corruption?
Are there any fixes to this problem?
Could it be my 3DS XL that is part of the problem? Recently it froze while playing Pokemon White 2 and has had a few glitches previously (just really slow for a few seconds of the opening of Pokemon X). Also I have 32gig SDHC card in my 3DS XL.
Thank you.
