I am having an issue with invisible objects being in the way of Sim movement/interactions. It started out in a small area outside and has since moved into areas inside the house on both the 1st and second floors. The third floor and basement are unaffected. My sims walk around these areas and cannot interact with some items in the affected areas. This is my Life States Dynasty game and I am concerned that if this continues to spread there will be no areas left unaffected. I cannot place objects or walls due to the 'cannot intersect objects' warning. I have tried going into build/buy mode to grab and delete, but cannot find anything to grab onto. Moveobjects on has no affect. Using the sledgehammer only succeeds in demolishing the floor or wall, but not whatever object is causing the problem.
1st floor
I moved everything out and went a little fence happy, but the blank areas are the areas where I could not place a fence due to 'cannot intersect object'
2nd floor
Those three rooms are the only problems on the second floor, so far.
