As I like to take things slow (into my 4th year, fielding only Codex ships and Hunter-Killer, waiting on Mint and Summoning Circle construction, Printer and Refinery research), I have to admit my Geoscape activity is much the same as it was 2 years ago, not counting special missions, with very incremental equipment upgrades across factions (alongside old stuff). I've seen Star Gods only once. Is there some threshold at which activity will categorically change to weight Star Gods heavily?
Also, why is it that rebel mutants can't be taken hostage if they are unconscious at mission end? I've only seen them once so far, in a Euro mission, but I'll assume this applies to all encounters with them. I debugged to revive a few with medkits (for the faction research), otherwise the only hostage would have been the General.
