I was in buy or build mode when this happened i do not know. My sims house is not level to the street now. This is because of my mouse.
My mouse is a trackball Logitech wireless MXERGO.
It has a longclick on it *sorry*
You can hold down the left click to permanently hold that button, you can disable it again to turn it off *click the left click again. This must have been on when I raised the foundation to a unimaginable height. I tried to lower it again but could not get the house back to the ground. One or several rooms are off height because of the longclick.
I can not put furniture next to the walls in some rooms because of this. I would have normally just have undone this but now I cannot go back
Thank You

Yay
Somehow the game saw that I made a mistake and reset the whole lot back to the regular street level, but I used the hammer to delete the walls for the high raised platform rooms to reset the room back.
:-D Nice little fix that they have there. I have no idea how they lowered the rest of the house (EA genies). :-D
