Does anyone have a save file? I'd like to take a look.

Yes, I do. It's quite simple: just repeat turn 122. The Hive guards are defeated, the Hive itself is cleared, and there's another battle for the amulet against a horde of mummies. Restrictions: no buying or reinforcing troops from the Tower, all battles are fought by Terek, although you can use anyone to paint the village.
Write down the army composition at the beginning of turn 123, and if it's even close, I'll let you know ;).
Yes, it's a save file from the Warlord difficulty.
