Accidentally signed into my Google account on the second device first thinking I had already signed in on the original device. So instead of having it linked with my level 8 town hall (where I have made a gem purchase), it's linked with the post-tutorial level 2 town hall. Any possible way of sorting this out to have my level 8 town linked instead?
You can have multiple G+ accounts on the same device so you won't loose stuff like emails, calendars etc. Make an account by going to settings --> accounts --> add account --> google --> new.
To sign into it go to Clash --> Cog Setting Icon --> Disconnect/Connect to G+, if you disconnected press it again. Then you will be able to choose which G+ account you want to load. Choose the new one and then your village will be linked to it.
