Just a heads up if you're an avid wonder trade enthusiast! There's been another bothersome glitch floating around.
There have been rumors going around that people have been sending hacked, glitchy Pokemon over Wonder Trade. The process goes smoothly, but once you actually receive said hacked Pokemon, it TRANSFORMS into a “Mystery Egg”. This “Mystery Egg” acts sort of like a “Bad Egg” from previous generations. Basically it becomes an egg that can’t hatch. You can’t release it, trade it, or hatch it. The difference between a “Bad Egg” and a “Mystery Egg”, though… is Mystery Eggs can multiply. Mystery Eggs can corrupt the PC box that it's in and end up corrupting the Pokemon within it if they’re not moved.This is most likely due to corrupted Data that results in the egg being “created”. If you have a Mystery Egg, here are some of the things you should / shouldn’t do: 1. Do NOT touch the Mystery Egg! That means no checking moves, stats, anything. It may have an item attached, do not attempt to retrieve the item! 2. The box the Mystery Egg is in is immediately QUARANTINED. Immediately remove ALL Pokemon from the quarantined box. They can and WILL be corrupted if they remain in close proximity to the Mystery Egg. 3. Do not, I repeat, DO NOT attempt to withdraw the Mystery Egg. Do NOT attempt to hatch the egg either. 4. Your primary goal is to save all your Pokemon from infection. Treat a Mystery Egg like you would a zombie pathogen that spreads via air. Keep it as far away from EVERYTHING as you can. Thanks for reading all this, and hope you don't experience this.
