Hey, I never played the Sims. This was inspired by Harvest Moon NPC system (Or Modern Stardew Valley). They would go from point to point which is based on your design. Making NPC go to your house can doable but require an update for the plugin. So basically my idea is you have 2 routine at 9 am. The first routine is just doing normal work as the NPC always do. the second routine is the new routine that go to player house but here the trick, that NPC only use this routine only when a switch is turned ON. So that’s my idea.
