Ok, I hate to do this because it's a pain to do on my end, but please post your save.
This save from mid-April has the problem with the gym trainer (Cam Williamson) but from your comment I think what you're looking for is a 1.01 save with a large proportion of people down sick (i.e. higher proportion than 7/224). I've only got four 1.01 saves counting the autosave (which I reset to daily saving) and I'll use the console command to check them out tomorrow. They're all the same play through.
But the sheer proportion down sick at any one time isn't what I was talking about. If that 7 out of 224 (3.1%) are all down sick for over a month that
is excessive unless SCW cities are public health disaster areas. For comparison, in Australia the average employee unscheduled absentee rate for all causes is about 8 days per year (about 3% when accounting for holidays and annual leave) but only a tiny proportion of those would be off for over a month at a time.
But I'm talking about how it pans out in the game.
In the attached save there are two unemployed NPCs. Franklin Boone is an all-round loser and Mike Sanders has been too exhausted to meet up since just after he spawned some time in March. My most recent save is well into June and he's still too exhausted to meet up. Shortly after this save he was joined by another unemployed NPC, Noah Morton (opinion 1), who I tried to text the morning after I met him without success. He too is still not answering texts over a month later. From then until after I built my dressing room and seating area in May there were only three unemployed NPCs and two were permanently unreachable and remain so.
So in the save below there are 2 people (Cam and Mike) out of 40 contacts (5%) who I know weren't answering texts for months, but as I've only tried to text a small subset of that 40 it seems reasonable to assume the actual proportion of long term AWOLs is considerably higher than 5%.
I've also posted my modded config and room_types files in case they're contributing to the problem.
