I’m not sure if it’s something new, but I just found out about it.
“How to break any apartment NPC (on Sapienza)”
Step 1: Ring the bell
Step 2: Wait for the NPC to open the door
Step 3: Close the door behind the NPC, so he stands in front of his apartment/ door.
Step 4: Ring the bell again, or as often as you want, at least once
Step 5: The NPC will stand still and won’t move anymore, as long as you don’t touch him/ do anything suspicious in front of him.
Example picture following tomorrow
I’m not sure if Step: 3 is required, or if this works on any apartment NPC on sapienza but it should. It’s a bit creepy, especially on The Author, when everything is dark.
