Transparent Block Layer Around Hall Can Prevent Collapses

Category: KAG Client

Operating system: Windows 7

Build number: 872

Description: The inner-most layers of blocks that surround a hall, when removed, still register in-game as being present. Because of this, collapsing any structures that were once connected to the hall requires a gap of at least 2 blocks. As far as I can tell, back-wall blocks (both wood and stone) do not create this bug -- just solid blocks.

Steps to reproduce:
1. Build a structure on top of a hall
2. Remove the inner-most layers of blocks, while not touching the rest of the building

Screenshots/Videos:

This first screenshot illustrates the problem most clearly. I've outlined the block that, once removed, ended up triggering the collapse of this base in red. Note: the dirt-backed wall in the middle had no effect on this collapse, and neither did the slightly broken wood wall on the right of the blue, slashing knight

And another screenshot that shows this bug when a set of blocks is anchored on the side.
