[Bug][Rivals 2.0.01] City defenders out of city.

I saw the same thing. My city archers ended up in my army and I had a character Maya in both my army and in a city.

Just encountered same issue.

Happened when defending the city from a Looter attack. Prior to the battle, Nephaz was the only garrison. On the same turn, a Sentinel unit completed construction. After the battle the entire army: Nephaz, Sentinel, and two freebie archer city defenders was NOT garrisoned, but was standing on the spot where a new unit usually exits the city.

Those extra details do sound pretty similar to when my issue happened. Did you also get the army duplication?

Confirmed... sort of

Just loaded up to a previous turn and retried. As the new turn messages began appearing (spell finished research), I happened to have the map centered on my city. Just behind the 'pick a new spell to research' window, I could make out an owned army standing next to my city consisting of Nephaz, the Sentinel (that had just been completed this turn), and the two freebie city archers. After I picked a spell, I then saw the 'you're being attacked!' message window.

Finally, after the successful battle--which was on the city map--I verified that Nephaz had been duplicated. He is both in the city and is in the army just outside the city (he was the only garrisoned unit prior to the battle).

Interestingly enough, when I click on Nephaz in the city and try to move him out, the whole army stack from outside the city moves to the same position, the screen shows there are two armies on that tile, but clicking on the arrows to scroll between the two armies does not select anything else except the army stack. I individually selected Nephaz and moved him out of the army stack, and now there are not duplicate Nephaz's.

So Nephaz was the only one that duplicated on you?

Correct. Nephaz, who was the only garrison unit, was the only duplicate. The Sentinel unit that was built that turn did not dupe.

(I also received the city freebie archers as units on the strategic map. However, after posting all of the above I went back to playing, and found that they simply disappeared as soon as I tried to move them)

I've also run into this bug in rivals. For what it is worth I have also run into it in the previous version of the game as well.

I saw this bug on my current game yesterday.  As described above, defending army (1 mounted, 2 archers, 2 snipers) were left outside the city after the city was attacked and they successfully defended it. 

Yep, I have had it again since my original post as well. Moving the army back into the city seems to get everything back to how it should be, so I guess at least the bug isn't game-breaking.
