Almost lost my account forever...

Hoping i can get a better answer on here. For some reason, my game suddenly started popping up an option to accept or cancel another account by the name of Chief Davka. It is a TH1. I've been putting in a lot of time in this game the past four months, and I'm afraid I may lose it any time. The thing pops up when i first come on, and will do it randomly while i play sometimes. Im afraid I'll be tapping the screen one day, and that will pop up, and I hit the button without even realizing it. They told me to log out of my Game Center and back in to lock my village in with my phone. I've done it a few times and it still keeps popping up. If anyone knows how to stop this, I would greatly appreciate some help before i lose everything and get stuck with a crappy TH1 village with a crappy name to come with it.

Hello, is your base linked to a GC account? The popup message shows that the GC you are using right now is linked to a TH1 base.

You have to complete extra confirmations before it deletes your account, so even if you tap it accidentally you'll be able to cancel it.
