Thanks for the help, guys! :) I've checked all the cities and the stack is just nowhere to be found. I've resigned myself to the fact that it was probably wiped out somehow. Ah well it's my first game and I'm playing on normal difficulty so I'm still kicking ass anyway!! LOVING it.
I had three primary armies, one with two heroes leading. This morning I was playing for awhile, picking away at Procipinee's defenses, when I realized my two-hero army was *nowhere*. Not sure what I did? Searching the forums I don't see anything that would indicate a bug. The army was epic, and I never auto-resolve ... maybe I accidentally auto-resolved some battle with another epic army, got wiped out, and didn't notice? Anyone else experience this? <p
