Yeah, I battle Nikola before transferring to gold and the last time I have battle it, was last year.
I don't really remember when I have caught it the second time because it was last year. But its probably around April-May 2021<----(not sure)
Also I think the main reason behind this problem is that I release my Zapdos in silver and after that I transfer to gold . And I later learned that the pokemon can still be restored thats why I request a restoration when my main acc is in gold. And this problem happen because of that I guess.
My Zapdos was retrieved but it was putted on the silver account. Can you pls move the Zapdos From Silver To Gold Please
Here Is the Screenshot, Im not even a Sinnoh Champ Lol and I have this.
Please move it on the main acc
