I was down to the last day waiting for my lvl 19 stadium upgrade to finish but when I logged in last night it had cancelled and the money was back in my banks. This meant I lost about 10/15 million as I was saving to expand my banks for level 20. I have had to restart the stadium upgrade so I have over 6 days to wait again and another 15 million to gain for bank upgrades. Totally crap.
