Shortcuts down the left hand side keep resetting to default position.

Thank you for raising this. We will investigate.

Have you noticed any particular pattern when it resets. You visiting a certain page, exiting the game etc.

I don't think so - I close the game after I play each day and it doesn't always reset.
It's possible that it's after every update but i'm not sure if there have been as many updates as times it's happened...

It has happened once more since I posted the bug..

Thanks for letting us know more about when you have seen it happen. Our QA team will investigate further.
