Ranking Lost after Transferring Back to My Original Region

Dear Riot Games and Community,

I transferred my NA account (Summoner name: 100 Girlfriends) this afternoon to EUW server to play with my friend. However, after I transferred back to NA server, I lost my rank (was Gold 4 - 0 LP before this transfer) and in my profile, it displays me as unranked. After I played 1 ranked game, it gave me a provisional rank Bronze 2. This is very frustrating because I was just promoted back to Gold 4 yesterday. I hope this thread will be noticed and the bug will be fixed. I really want to see my original rank to get back since I put so many time and effort to get to gold for past few months. For other players, please be aware of this potential bug when transferring. Thank you.

Sincerely, NA Player: 100 Girlfriends
