hi @crinrict!
i've been at this again, because i've been very ill and at home. so as my flare-up allowed, i decided to write a detailed example of what keeps happening in my game.
today, i edited (only clothing) a new townie i saw on the "other" bin. she had no job, wasn't a co-worker, was never seen around town/venues, as a walk-by, etc.
i know this because i check the townie bin all the time (last time was yesterday, actually, LOL) and she wasn't there--today, she stood out immediately because she was really pretty, but also because she had a backwards cap on, which i'd never seen on a female NPC/townie before. anyway, i didn't like her outfit, so just for the sake of it, i changed it.
(previous to finding her today, i hadn't deleted/merged anyone from the "other" bin in a long time. only watched it, and saw them spawn which, like you said above, isn't a bug.)
but back to editing: after i changed her clothes and left CAS she, of course, was added to "my households" and marked with a heart. i removed it and she went back into the "other" bin. and when i looked there, i saw three more households had been generated. (i keep track of the last names).
i took one of *those* new Sims into CAS, and changed her outfit. after i saved her, i removed her from "my households" and then looked in the "other" bin. two new households were there.
so i took one of *those* newer ones into CAS, and changed her clothes and last name, all of the same steps as above. i checked the "other" bin, and saw, again, two new households.
i checked the names and, instead of editing any of them, i loaded my own household. i was hoping (i always do, LOL) that *maybe* i'd see any of the newly-generated ones at venues/walk-bys/etc.
as usual, that was not the case. this is what happened: when playing my household, i see yet two new Sims at a pub. i go back to "manage households" and see them in the "other" bin. editing one of them, this time, doesn't produce any new ones. i go back to my household and travel. at the library, i see the usual librarian and three Sims i have created myself. after a few Sim hours, i travel to the museum. every Sim who shows up is either one of mine, from other played households, or a regular NPC who's been around forever and knows most of my Sims. i have my Sim stay for quite a few hours and this pattern continues.
i never saw any of these townies the game generated--not even the pretty, cap-wearing one that was the first i edited. :'(
i don't know why this happens. i play in different venues at different hours. i see the same bartenders/waitresses/trainers/librarians/etc. every time. these newly-generated Sims are nowhere to be seen, anywhere.
sorry... this was *so* long and maybe not even useful... 😞
