There seems to be guilds war bug where when you get hit or chained in war it disproportionately affects (takes away) guilds but not other buildings. Obviously this is hugely disadvantageous to races like dwarf that use quickfeet, have a low elite value so use anon, etc.
Have confirmed from multiple people in my kingdom this is the case, and I'm warring another dwarf kingdom that's relatively known and should be able to confirm this antecdotal evidence (as I don't play dwarf myself)
But it seems unusual that someone who previously had 10%+ guilds, loses less than half their land and now has 2.2 % guilds. Have heard this complaint from many of my kingdommates over the past four days, and I wouldn't waste your time without something legitimate.
