Mines refusing to connect from one side.

The mine tile in question 

When mining the tile inbetween the rock piles, mining upwards from bottom gave "[20:04:23] You hear falling rocks from the other side of the wall. A deep shaft will probably emerge.", saying that the tunnels are too far apart slope-wise to connect. Mining downwards from the top however connected the tiles just fine. I've had tunnels that were the other way around, having to mine from the bottom up-wards to avoid that error.

Wasn't producing rock shards or connecting the tunnels when i was mining from the bottom and getting the message. Never gotten a message before creating a drop shaft either.
