I'm on either 4, 5 or 6. I lost count somewhere, Lol.
As for my problems, I'm very hopeful now! I wiped all memories and now they live on an empty lot, everything important is in the Inventory until I start the rebuild, I tried controlling them for a few minutes after I'd done it and they were much quicker at responding!
Chuckles, I play in SV so most of the Car Spaces are on the Rabbit Hole Lots mainly. I did have about 7 Stereos on in the House alone so that might be one of the additions to the lag. Memories didn't seem to affect the Size much however I had well over 350 amongst them and probably nearer 500 Memories.
Original File - 211mb
No Memories - 208mb
No Memories or House - 142mb
When I was going through the sheer amount of the House that was purely decorative, I really have to start thinking practical over showcase.
Now to rebuild... for the Third Time in this game, Lol.
