This bug it happened to me today while I saw a announce in the roulette, I minimize the announce window, later I return again to open the announce window, I finalize the announce and when I return to the game I had everything for buy again in the talents, salesman and marketing absolutely everything.
When I bought everything again my cash was so much, above the average of my level.
I think about I can unlock all the properties or the most.
In the next screenshot you can see the difference between the money earned and the cost of next property
Note : I unlock an hour ago two or three properties
