Red tiger doesnt save, its predetermined so as soon as you close the game, you will reopen and it will be a pop up box with how much the bonus would have paid.
I’ve seen some people do hunts and the bonuses go missing, but also heard that it’s because they were collected on the mobile version, and they were playing the desktop version.
Check with the casino if you can bonus hunt if you’re planning on doing it with bonus balance, because now many will allow it.
