I used to get this regularly, regularly losing the bonus, and this included losing the Grand Casino version and on contacting GI they advised it was because both versions were on the PC. I took the Airport City version off and kept Airport City GI on, and it was all good every week thereafter. GI gave me some greenies as compensation for those lost. Worth dropping a ticket for the bonus missed.I had a look at the apps on my pc, there were two versions of Airport City installed, 1) Airport City G! 8.41.01, and 2) Airport City 8.42.01, I updated the game to the current version yesterday but because I didn't remove/uninstall the old version, it reverted back to it when I relaunched the game. I have since removed it so it can't do that again. Everything seems to be working now except for the fact it wiped my weekend bonus code off and I can't reclaim it.
