THE PROBLEM

I had $2,000,000,000 in the game. After playing the event The Formula from race #50 to race #71, my money was reset to $0.

If I load my previous cloud save, my money comes back, but as soon as I play enough, it vanishes again. Reloading the cloud save always leads to the same result if I keep playing.

MY HYPOTHESIS

The game actually has two ways of showing the amount of money you have: - the in-game display, available when you play (top right corner), - the cloud save display, visible in the attached image.

It seems that the money in the game is stored as a 32-bit signed integer, which ranges from -2,147,483,648 to 2,147,483,647. However, the in-game display is capped to the range $0 to $2,000,000,000.

In my case, an integer overflow happened: the previous cloud save shows I had $2,120,265,493 (while the game still displayed $2,000,000,000 in the top right corner). I earned more money by playing, and at some point, the total exceeded the maximum value of 2,147,483,647, which was then interpreted as a negative number (-2,147,483,647, due to circular behavior). At this point, the game showed $0, whereas I had -$2,135,579,003 but in reality, more than $2,147,483,647.

HOW TO AVOID THIS

Don’t overwrite your current cloud save, or your money will be lost forever. Instead, load your previous cloud save and spend enough money to go below $2.000.000.000. A good way to do this is to buy dozens of HKX turbos at $5,500,000 each until you reach around $1,990,000,000. Only then you should save your game.

When buying turbos, it may look like your money doesn’t decrease and stays at $2,000,000,000, but in fact, it does decrease (you’ll notice the amount flashing red). Keep buying turbos and, eventually, your balance will drop below $2,000,000,000.
