Crin, just wondering OP states this all happened when deleting the wolfe house and putting another house there. You think he cause a routing problem in the game that could have damaged the video card? Like we discussed before no one know how EA programed this buggy game.
I did have an issue where I moved sims while they were pregnant, caused female children in town not to age. Had to delete all the children and that got rid of that bug but the bug attached itself to the house so I moved the sims to a new house. The old house still remained with a bug and i could move no other sims into tthat house. I bulldozed the lot completly, added a new grid, put a new house there but still could not move any sim on that lot. So I left the lot empty. Its like all these chains of events caused a routing problem. I had no issue with my video card though.
