Yes,
RonD, this is the right place. It isn't named the Bug
Discussion Thread for nothing.
The dominion spread entry looks very much like a fix for both Vanishing Scales and the erratically spreading dominion that sometimes appeared all the way across the map because they were essentially caused by the same thing, a corrupt geotable. It is unknown whether it affects some of the other issues related to Dominion spread. Both Johan and Kristoffer have made comments to the effect that the scale bug has been crushed underfoot and it was indeed thanks to the contributions of the people on the forum, notably vfb and calmon.
Stygian Paths, looks like it could get a long awaited fix, but to be honest, I don't know the specifics.
