v185, Furnaces on the north and west edges of the exoflame's area (viewed with manaseer monocle) do not work, while furnaces on the east and south edges of the exoflame's radius do. All furnaces are in the exoflame's range, this has been confirmed at least 12 times (the building was built around the area). Tested with floating and normal as that was thought to be the issue.
