As the title says. I forgot to take a screenshot, but thought to come here and report it anyway. Basically an enemy ruler was parading through my lands, and when I went to attack him, I couldn't because he was standing inside of a "ruffians and monsters" faction enemy.
On a similar note, I just did a 40 hour marathon on normal world difficulty, normal AI difficulty, and the monsters/ruffians faction never, ever attacked any of the AI during the entire marathon.
In several cases, I would see an AI pioneer standing next to a "deadly" monster of some sort, just cloudwatching together in harmony, and then as soon as I moved any of my own units there, the monster would immediately make a beeline for my unit.
"Hey look! It's Player 1! Get him!"
I really hope that gets fixed, or else multiplayer gets added. I really want to play a game of fallen enchantress where I know that all my enemies are playing the same game I am, with all of the exact same difficulties and hardships. I have loads of friends who would buy this game if it had multiplayer, I think stardock are doing themselves a huge disservice by not adding it.
