I was messing around with the mining in Alpha 8. I was trying to make multilevel areas on the side of a cliff like steps and the in game grid had gone missing. The cliff looks like one solid mass and the entrance in the cliff is gone even though the tunnel is still there. I also got a pop-up that looks like this:
Uncaught TypeError: Cannot read property “children” of undefined
Steps to reproduce:
Place a single wall against a cliff.
Wall is placed next to a cliff.
Cliff voxels blend as one mass.
