Mineshafts in Under-city

[Ash]

Has anyone had them spread your under-city to an adjacent region? I've had two of them for the past 35ish turns and neither under-city has spread, I've not got the debuff from spreading under-cities with an agent either. Am I just unlucky?

yep had one spread to, two other regions within 5 turns. I was like wow this op, but guess i got lucky.

Cheers for the heads up. I won't scrap them then. :P

Do you get a notification when they spread? As in, do I have to manually check if it triggers?

You will get a notification via the events tab whenever your under-cities spread

I had it relatively quick (with just the 5% chance per round) and it did spread from Altdorf to one of those minor settlements

You get a notification. Im keeping an eye on my undercity spreading out from lothern (i shoulda gone for that one on the island in the centre though for a better spread i think)

Using Doom ritual and picked large city, spread from that city to two small towns and then one more spread from that small town to another. Also interesting is later they found the primary Undercity and said that the faction had the option of destroying it, if they had enough money. 23 turns later and that exposed Undercity is still active and have upgraded a few things. Concept is interesting and is keeping Queek in food.

If you make a lot of under empire cities and make the 10% to spread buildings in all of them it can get quite impressive with it seemly spreading every few turns unless you get unlucky :P (Just make sure to scrap said building if all adjacent regions already have a under empire city).

I've had another 20 turns of neither under-empire spreading, that's nearly 55 turns of 10% chances of spreading, and nothing, I think I shouldn't go outside, I have a feeling I'll be struck by lightning the second I step foot out. :|

You might just have found a bug that causes them not to spread :P Are you playing a old pre-patch save or did you start a new game? What lord are you using? Etc?

Of course it might be that you have just been really unlucky as well :P.
