Greetings,
To add my two bits to the fire...
everything was great last night, installed the patch and not the simulation is lagged out, and trying to move a house or household into the bin never stops processing.
I have seen this type of simulation lag before, well all the time, at 5am sim time, when the plants grow. The animation for the effects (ex. fire, smoke, sprinklers) still do their thing, but clicking on thing has a delay for the menu to pop up and the sims are jerky in their animations and actions, but that clears up and currently it is 6pm in my save.
As for the lots not saving to the bin, I am lost on that one.
I really don't want to have to reinstall everything to be able to play again, so maybe release or post a patch here that will revert 1.55 for now... please
