So I have an old Pokemon Pearl game where I've clocked over 650 hours on it, but I purchased Pokemon X recently and haven't played Pearl much since. I didn't want to lose all the Pokemon I worked to get so I decided to transfer them to Pokemon White via the Transfer Lab and then onto X via Transfer and Bank.
I'm normally very paranoid about losing my Pokemon due to random problems or bugs so I also do tests with a Pokemon I wouldn't be afraid to lose.
I went through the process of using my DS Lite and my 3DS to transfer my Pokemon from one game to another using the mini-game and completed it successfully. Then I used Pokemon transfer only to be given the "Attention! There is at least one of your Pokemon in the Box that cannot be sent. A problem has been detected with one of the Pokemon. Sorry. The problematic Pokemon cannot be sent" Then it shows me that NONE of the Pokemon in the box can be transferred.
I don't understand why though. All of the Pokemon in my Pearl game were legitimately caught. Nothing about my Pokemon is hacked or illegal and I'm really annoyed that I'm getting this error...
Does anyone have any idea what the problem could be and how I can fix it?
TLDR: Pokemon Transfer is being whack and not letting my Pearl Pokemon into X.
