While I was exploring the Tower on Saturday (7/26) I found that the robots sweeping the floor in various places had no body depth to them unlike other NPC's who had depth and occupied space. It was fairly amusing to be able to place your guardian in the same place as the sweeping robot and see his face on your body. Now I wish I had taken a screenshot of the error. I'm still fairly new at using the share button on the PS4 and learning how to get that image off the system. Hope this helps y'all flush out the bugs.
