I attempted to upgrade my stadium for 23 million in cash which was going to take almost five days, i took plunge and clicked upgrade at which point money was removed and upgrade started. I left the app but returning a few hrs later i noticed my upgrade had ceased completely and i was still lvl 14 stadium but the 23 million was still gone from my banking this has to be a glitch that needs looking into. Has anyone else suffered anything similar while playing this app.

haven't seen this before, suggest you log a ticket rather than wait for a reply on the forum

First of all, refresh the game - if that doesn't work, raise a ticket.
