I'm having the same problem. Error messages after winning a game, not enough money to upgrade ect.. Loosing lots of money, and and gems.
Update:
Property 1 - 7 have blue hotels, i.e. are fully upgraded, property 8 is in construction mode. I completed the last update on property 4 (orange) Monday before leaving the game until after midnight. For several days I have not encountered error messages when playing Sudoku nor when collecting money.
Just now (Tuesday), my first Sudoku won 5 million but I received an error message - the amount was added to my daily goal but not to my total earned. The second Sudoku won 6 million ish but I received an error message again. When I clicked away the error message, the amount was added both to the daily goal as well as to my total. Both times, while I played the Sudoku, at least one of the properties became ready for picking up money; I am not sure if this is related to the error message.
After the second error message, I cleared cache and rebooted my computer. Game three should have paid around 1.5 million, but the error message occurred again. Like with the second game, clicking away the error message added the amount both to the daily goal as well as to my total. I refreshed the game and have lost the Sudoku money from my total. The daily target does not seem to be affected.
It is frustrating and I hope that upgrading property 4 (orange) has not lead to the problems.
