Ok...here's the steps:
1. Got to be in sneaking mode
2. Encounter hostile/scared animal target
3. You have to be
Spotted and/or attacked
4. Take out target (with or w/o help from companion....not sure, let 'em get a hit at least)
5. Companion will somehow "Lose sight of you" and just stand there. To check talk to them and you will see:
It's as if they're in town again...
Want to check? Sure...just 'T'ravel:
For science's sake I continued to obsherve the creahtures in thay're natural habitat. Crickey! The buggah's seem to be heading to a local Elven town ruin!
And I lost sight of 'em in Travel mode. I circled around to be sure and I then entered the Old Ruins, destroyed in a Elven-Human War that is still goin' on so that's probably why they didn't go there even when it's nearer, and suprise suprise:
The drunk guy crawling in the ground is my first companion that I lost the old fashioned way: when he got distracted chasing wolves & monkeys. But alas, they will automatically join you again if you "find" them so I just redid the ol' trick to lose the buggers.
Extra Notes:-This is an old save, it's my 1st Kobold adventurer from earlier versions that I kept on transferring to updated ones (currently using .11 or .12) & one side effect of it is that even though I am covered w/ scars, I can no longer see that descriptions (Although the body parts with old wounds still have colored text.
So this may actually just be an anomaly or weird glitch. Do try it yourselves and share your results.
