Managed to open the crate with 3 Master Builders very early in the game... way before my thorny bushes are cleared.

**Spoiler** That Gong in the crate has gone missing. Am I going to get it when I've cleared the bushes?

I can't believe this... I've managed to get FOUR Master Builders in my 2nd village and it's still a relatively "Young" village.. My 1st village, which has Level 3 of most Aspects and I'm STILL struggling to get enough master builders to open the crate!! I was waiting for just ONE more Master Builder only to have an Esteemed Elder go to Isola Heaven!

I've got to wait for TWO now!! Typical!!
