Thanks for the warning Blueblood - I'm in that situation as well. I generally dont use fences, so I guess I'm safe. What kind of crash are we talking about here?
It crashes the whole game to the desktop.
Couldn't you just remove the entry for the rocks that you do not have, in Simpe? That's what I did with the last CEP, so that I could see the missing K&B recolors, and removed the extra pool light entry to avoid crashing.
You could probably do that. I just used the autoinstaller and unchecked the garden rock fix though.
