I have a city that I built right next to a dungeon (with a hard quest). As a side note, I've never been able to play a game long enough to get to a research level where I can actually DO a hard quest. Anyway, I clicked "eject" on my sov from the city, and it sent me straight into the dungeon. Thankfully, I didn't have the tech, so I got a "You can't do that yet" message and was OK.
I think that ejecting from a city should NOT place the troop/sov/unit directly into a quest. That's just...ouchy. I would really like to see a "troop rally point," like what is in, oh, every other game. Sins, Civ, Rise of Nations, RON:Rise of Legends, Stronghold, etc. and so on and so forth and you get the idea, forever and ever, amen.
By the way, I think you can see that city in one of the many crash reports I have uploaded. It's "Game3 Save-0_86.EleSav". If I didn't upload it, and you need the save file, let me know - I will upload the save file.
