So I'm playing Turkey and I'm slaying with these city state levies. I meet Persia and Ngazargamu is plenty hale to levy and wipe them out. I have one turn to go before I have enough cash to turn them and more than half their army just vanishes into thin air! No battles no nothing. The first screen shot is 14 gold away being able to levy. The next screenshot is the very next round. I remained suzerain the entire time, so there aren't any hiding in the fog. Is this normal or this just the most unfortunate bug timing in history? By the time the army builds up enough to be useful, they'll have walls and a lot more preparation.
