No worries about the toon, though I didn't backup the save, I do have other older copies of the save from 3.3, 3.4,3.5 versions.
Some of those have longer life spans as the "Njerpez camp" appeared in this save from my Steam version of the game.
Once I had 'spotted' it (Note: it did not tell me that I saw a settlement) Saw it after resting in a fishing shelter I have nearby when I hit F6
Found a lone Njerpez warrior at the edge of the clearing (Should have probably run at this point)
I sneaked up but only saw one wooden structure, though the clearing looked large.
I think I killed 3 before I took a 39% spear to the neck, then things got hectic and someone got behind me, the engaged count was 5 and a steam of 3 were still flowing down from the North.
I would have probably been disappointed if it would have ended any other way.
