Miscallenous thing, but the entire time of playing 47.xx all the way up to 47.04 and about four or five fortresses (whether they were successful to keep playing or not) i have not seen one foundation of a economic site dwarf hillocks for me to connect to and send/recall dwarves rather than elves & goblins travelling great distances to found their own often soon to be hostile sites.
Im starting to think that dwarves cross migrating/currently spying are confusing the system or some other factor.

Forests have a overlap through elves and goblins (everywhere else) so it would be interesting to see if restricting dwarves to a parallel biome_support of hills & mountains only would work,
because breakneck speed baronies a big burdens. Its not like we can engage in any sort of guranteed tribute approval from the economic site anyway.
It actually gets worse from that point if you kept playing that attached URL, i forget but I think i got up to 250 non-dwarves attached since there was a big rush to settle near me.
