Apologies in advance if this is old information, but I'm quite sure raiders are being replaced as scavs. I did a few runs on Reserve attempting raider-kill tasks & eventually saw in my post-raid kill list that there were quite a few names present which indicated they were raiders (according to EFT wiki) but the list categorized them as scavs, & resulted in no task progress. The other mod I'm using is AIO which has the "Chomp-RaiderSpawnFix" option enabled, unsure if that's interfering with it.
I also haven't encountered a single rogue after 7 runs on Lighthouse, exploring the water treatment & cottage areas, whether that's relevant.
Lastly a side question, sometimes I've noticed regular scav names tagged as "Boss" in the kill list instead of the regular "Scav", does that mean something specific?
Thanks
