This gets more fun!

One army, in two locations!

Tearny and Badra were fighting a rather large mob of Corpse Spiders, which ultimately resulted in Tearny dying and Badra, well, not dying (but the combat was still lost). Tearny was left immobilized, seemingly stacked with Badra in the middle of nowhere (which also immobilized Badra).

However, I noticed a small wild mob over near New D'kay, and clicked it, intending to pull the Defender stationed there out to kill the mob. Instead, I find Tearny there, not immobilized, and so I decide to use her instead. Upon entering the fight, though, I find myself with Tearny... and Badra.

This is what greeted me when I got back to the strat map.

I saved and reloaded, and now Tearny and Badra are correctly occupying one place, on the map over by the spider lair.
