Check if Ostland hasn't become Heretic. It would explain everything, especially why everyone hates them now.

If they have an alliance with some Chaos Factions, it's sure then. Kill their leader and they probably will become Sigmar servants again.

ignore the two idiot trolls and as to your question, no i dont think there is a way to change it. the only thing you can do is to reload from a much previous save and hope it doesn't happen again. the cause of this break in alliance is bug in medieval itself i think. what happens is that there is an army in ambush mode and when the ally is passing that route the ambush army attacks its ally and this causes the break in alliances.
i think the only way to fix this is to remove ambush.
