I get this sometimes when I’m play-testing a build. It usually turns out to be something super tiny - like the bed I placed with MOO just needs to move a fraction over and it’s fine. Or, the bed itself is fine but there’s a tight spot somewhere along the way TO the bed and the sim won’t squeeze through. I had that in a bathroom I was building just tonight. With MOO off, the game let me place my shower, sink, and toilet, no problem. But when I tried to send the sim to the toilet…nothing. Like you said, no waving of the arm and complaining; the action just dropped from the queue and nothing happened. I rearranged the bathroom (it was too tight a squeeze between the sink and shower which blocked her path to the toilet) and now it’s fine. So maybe try wiggling things around a little with MOO off. I find it’s helpful to click the floor along the way, doing ‘go there’ until I find the exact spot the sim can’t ‘go there’. ?
