Hi!
In the latest version of Aielund the civilians are hidden at different locations. If you are looking for them where they were in the older versions, you won't find them. Have you looked everywhere?
Or are you playing on Hardcore Difficulty? In that case it is possible that area of effect spells killed one or two of the Dwarfs, happened to me once, I had to go back to a previous save.
You can check in Debug Mode for any remaining civilians in your area
Type in your chat bar
##DebugMode 1
and then hit the period key (.)
In the opened Window your current area will be highlighted, open the creatures submenu and check the entries for Dwarven Commoner or Noble. Then you could click on their entry and the "Jump To" button on top. Or close the window and go looking once more. Either way, don't forget to disable Debug Mode:
##DebugMode 0 (in the chat bar)
Good Luck!
