Oblivious without perks/addons?

So is there something I’m missing here, because I could have sworn that the oblivious status affect had to show up (icon that you have it), and you had to run a perk for it? So how am I not seeing red or hearing a heartbeat against a killer that’s running lightborn, tinkerer, discordance and agitation? Did an update happen that made this possible, or is it another bad bug? No add-ons besides one’s that make Blight run faster after each rush, so couldn’t be that! Also happened two matches prior with a Huntress, same incident, different perks (still nothing with oblivious)


UPDATE; for context no gens were being worked on, it was end game and I was trying to get the other survivor out, I was self-caring as she fully recovered! So I don’t think tinkerer would have activated? Everyone else died.
