It's impossible to tell multiple units to leave a city.

You can see here I've both units selected.  (Good thing that quest gave me a Knight...  It would've taken me forever to get guys of my own out.  Also, please inform me if the image is too small.  I've never uploaded images to a forum before.)

Now, watch what happens when I tell them to leave the city together.

The Knight makes it, but Vindalyn (My Sov,) does not.  Furthermore, her figurine has suddenly started appearing on top of my city.  That's two problems for the price (and effort,) of one!  =P

Lastly, there is one more Graphics glitch I'd like to report, specifically regarding the Animations/Stances.  Upon creating this Sov, I gave Vindalyn the 'Bandit' animation, which worked fine at first...  Until I equipped a Breastplate.

And now she's a scarecrow.  =P  (I can't help but chuckle at that though.  Also, yes, her movement is accurate...  Which is going to be my next bug.)

I also come across Endurance and Dexterity potions far too often.  It's turn 24 when I took the immediately preceding SS, and Vindy has a movement of six...  SIX!  After adding her Dexterity (Too many Dex potions/buffs too,) she had a total movement of 10.5 tiles PER TURN!  She was moving like a Cheetah on Crack-Cocaine, Meth, and Speed, all at once!

I don't know if this is also a bug or not, but a lot of the Goodie Icons (I wouldn't call them huts,) that add a slight amount of Dexterity do it for all units on the map.  (At least, all of my units...  I tend to doubt my finds apply to the AI's.)  After some decent exploration, it's not uncommon for every unit I own to have upwards of 2.5 Movement/turn, and that's if they started at 1 Movement/turn.

Lastly, the Auto-Explore is messed up.  You can't set a unit to Auto-Explore for several reasons...  They'll endlessly try to move into unmovable tiles, making them worthless for exploration as long as Auto-Explore is on.  They'll also endlessly move into occupied territory, causing the "Lo Traveler, get away from my Empire!" message to pop up endlessly...  I do mean endlessly...  They will NEVER, stop trying to move into the Occupied Territory, and the only way to fix it is either to declare war, or go into the Diplomacy Screen, exit out, and manually move your unit.
