The 1179 (not 1279) BC saved game had 19 ghosts. How did the extra 12 ghosts form?
The major devolution in 1179 BC (of both fancy residences and stately manors) was caused by the bazaar running out of linen and later pottery, not from losing dance coverage. Perhaps the buyer from the bazaar in that block failed in the same way that caused my
original Immortal Iunet to fall apart (as described in reply #67).
I don't have time now to look at how the ghosts were eliminated, but expect to do so within a few days.
