Hi, I'm on my 3rd generation in VF2 and they won't pick up socks anymore. They used to pick them up but now when you drop someone on a sock it says they're picking it up, they bend over to pick it up, but then they just stop & wander off leaving the sock where it was. Is this some puzzle I'm supposed to figure out or a bug? I did recently clear the sock pile in the bathroom, not sure if that's related.
