So, after testing, and searching around the internet, wiki, asking on forums, ect. I still have not found an answer, and im not sure anyone has yet... Which is why I decided to make a separate thread with this issue, and not for just my sake, but everyone else as well who attempt to find and search for an answer to this issue..
The issue is this:
When Civs and new Civs are modified/added to the game, (Such as humans, elfs, ect.) They always wont want to create economical settlements close by to your fortress as it would work as Dwarf Civ. There are chances of nearby Cave inhabited Civs joining you, but without this chance, you cant achieve Baron, ect. Has anyone found a solution to this issue? Or know what is the cause of this issue?
I tried testing to see if [SETTLEMENT_BIOME:_] tag had any reason with it, but after 4 years, the only thing that by chance that economically joined me was a nearby cave Civ that was similar civ as mine. (testing things out as a human, but that cave had a civ that lived in town/halmets). Not sure how well I would say that isn't a tag that solves this issue when I've only done 1 test with it.. but Wiki, ect says nothing else about that tag. I have also checked Position tags to see if there was anything relavent with the issue but there doesn't seem to be one. I double checked on DF wiki again and looked up the requirements for settlements to show up and join you, but I met all the requirements, even the generic "hills or grasslands" req that would be there for dwarfs, since my humans show up and have support living there as well, and there is plenty of space as well.
Anyone else know any info on this issue?
Edited:
Known ways of achieving economical links:
1. Close nearby Cave Civ randomly being linked with you. (happens half the time)
2. Having Other Civs conquer another nearby site near you. (only 2 cases recorded as of typing this)
3. A Chance of your members that recently took over a location, to move away to make a new site. (only happened once for me)
4. A Civ that is the same as yours that had their site depopulated may repopulate and change to economically link with you.
5. Taking over other locations (unconfirmed)
6. A Chance of a site appearing after you retire the fortress.
If anyone has any info, let us know!
I wanted to make this thread to help those who are searching for this exact issue!
