Total holdings after winning the cashew

I won 4th and 5th place prizes in the cash event, so my total holdings should definitely be over 1,000. But the next day, I always see the total holdings cut in half to 500. It's not a joke, it's making me angry. If you're going to do that, then don't show the total cash holdings at all. I worked hard to get it, and then it disappears the next day—what a shitty reason. Damn it.
