Does auto-resettle apply to the Borg as well?AI doesn't resettle. The new autoresettle feature helps a bit there.
Technically speaking AI can't ever resettle. At best you can write an event that pretends to simulate it (teleports pops and deducts costs. And I don't think you can track the cost from script so it will be a bit off), similarly to the how automatic pop migration mod used to do it for human players.
I was under the assumption it only works for non-Slave, non-Gestalt Pops (or if Migration Controls are disabled).
