Cave-in under stone column in natural cavity

By natural cavity I assume you mean you found a gallery that opened up when you were mining?

were there some cave in boulders around before this cave in happened?

Also, in Salem it was still possible to get cave in within support range (you needed 2 supports to have 100% guarantee it would not happen). Depending on whether hafen uses the same code it be like that here too.

Yes. Cave-in happens while i mine tiles in gallery.

were there some cave in boulders around before this cave in happened?

No. All boulders are from this cave in.

Also, in Salem it was still possible to get cave in within support range (you needed 2 supports to have 100% guarantee it would not happen). Depending on whether hafen uses the same code it be like that here too.

My first use of stone column, but cave-in never happens with me under wooden support range in w8.

Could you detail more exactly what happened? You opened a natural cavity and that caused a cavein, or...?

Look at the picture above.
1) Placed stone column.
2) Mined few tiles and opened gallery/cavity.
3) Mined a bunch of tiles (30-40 ore items) from gallery walls.
4) Suddenly cave-in happens after another mined tile (not sure if gallery wall or tile next to it).
Earlier cave-ins never happens under wooden supports. Not sure if problem is stone column or gallery walls.

After a bit of testing I noticed what is happening is the Stone Mine supports have less range then what is displayed it seems im constantly able to make cave ins happen 1-2 tiles before the edge of the range plz fix?
