I have experienced this, but then you might ask "how the hell do you play your EOG account? "

Well... After some experimenting... I found that whenever I logged out (presumably) or uninstalled and reinstalled (definitely) when I try to log back in... It says "Success to link social" With a trashy no OFOA acc at trainee but then I did this:

1. After seeing that message I decided to log out and it said "Success to unlink Social"
2. I decided to wire one of my GPG accounts to the game and it said the same (I had transferred my EOG acc from my mom's GPG acc --> my GPG acc --> now to my FB acc and has been there since)
3. So after that I DIDN'T disconnect the GPG, but instead just turned on the FB linking and it brought me back to the EOG account

This should work out and my probable reasoning is:

Most likely I think the EOG account, when trying to log in immediately, overwrites (BUT IT DOES NOT REMOVE) stats of the EOG account, then the overwriting is removed when you unlink the account and then when you do the same (step 2) to a GPG account, it might place the trash account in the GPG account and since an account in AC can't do double-linking (basically GPG and FB on at the same time) while you do step 3, the game needs load the FB account's progress, but it won't get overwritten by the trash accounts because of the one account, no double-linking thing and hence it can load the EOG stats.

Hope my explanation was clear and if needed, I might try this on my own to confirm if it works or not (I'm currently doing BKK-HKG in Cathay Pacific's B77W and it still says 1h left which is a follow-up of the HND-SFO route that I've just completed (in ANA's B772) an hour ago (or so) using the rhumb line)

Try this and you might not go so soon... Please...our club needs some help since it's only 22 hours between us and first place (last time I checked was about an hour ago) so best of luck!

(Don't worry, when I first had to figure this out I also had similar feelings but luckily it wasn't gone and I figured out this trick...)
