I never denied placing them nor will I. But again i was met with"From your explanation I can only assume that your balance wasn't fully updated at your front end, but after seeing the lost bets you can clearly see where the funds are gone." And as to the calculating my own bets and not relying on the balance displayed. "
When you press "bet" on plinko, the outcome of the game is calculated and you are paid. But the visual payment is delayed to be in sync with the ball falling between the pins.
To understand me, do this: choose automatic bet and change the browser tab, or minimize the browser, and you will see all the ball getting together in the board. Once you resume it, all balls fall at the same time and you are "visually" paid. Now, try again, but instead of resume, just close the tab. When you get back to Stake, your ballance will be updated even if the balls never reached the prizes.
Some time ago, if you placed a bet too fast, you can see yourself playing with negative balance; it was because the delayed interface.
