Expert Mine 3 Level 78

[jm28121977]

Hi everyone

I hope someone can help me. I have played level 78 of Expert Mine 3 over 11 million times now and I'm always one emerald short. This series of mines always has solvable levels so I think I'm probably doing something wrong somewhere. I've scoured the level in the editor and check the Yams' configuration but nothing leaps out at me. I'd be eternally grateful for any pointers.

Lots of love
Jamie x
