There is a little bit of a ramp up with the events so if you are able to do the mission quickly, you can avoid some of the "nasty" stuff. Stay a little too long however...
All right, I have indeed experienced some of these events that you eluded too and I'm pleased. Though they have really only happened in the showers. You have said in the update notes, that there are small and larger chains. What does that mean exactly? Like ones that end in sex and ones that don't? I've seen one so I think I know what you are referencing as it happened when I searched the beds when no one was there.
Also, do these events transpire within the storage room perhaps? I'm really enjoying this game and I can't help but want to know more. Though if you want me to just find out for myself one last hint would suffice.
Sorry for late reply, only just noticed you posted again.
Larger chains are events that take place in sequence. Letting your mood get too low and triggering the Viktor chain for example. Each time you visit him, a new sequence in the chain is played.
Other areas that have event chains are if you search the dark and damp room at night.
Can also find events in the storage room climbing u the shelf or opening the vent. There are some when you try and pry the pipes in the utilities room. Sleep events and general walking around events.
If you are using cheats, raising your stats will make you avoid some events and cut short others. So don't be so eager to bump your stats up too high.
