Hi, Rell here.
1. Fixed a bug where bookends you were holding would disappear after saving and loading.
2. If your save already lost bookends, they'll be returned automatically when you load it. You'll find them back in the bookend box — and if you'd already put that box away, the box will reappear too. You can continue and finish from where you left off.
The launch issue (black screen, then crash) is still being investigated. If you're affected, the workaround in the previous announcement may help.
I'll keep working to make the game better. Thank you!
