Going upstairs

[Indiasong]

I just loaded a lot I have already played a few times.
The sims can't go upstairs unless I click on the stairs go upstairs. Or downstairs.
And they get stuck in places where they shouldn't, and they seem not to be able to go to certain places.
And i had to delete and buy new bowls. I played with testing mode on.
I used the lot debugger, no change.
Then i used the debugger with debug mode on, and I had to shut down the computer to exit the error windows.
I'm getting really worried here.

Do not use "Force Error.../" options while the debug cheat is active unless you want to be spammed in dialogs. There are times when this is good, but usually you should turn it off before pushing that button, cuz there's gonna be a lot of errors.

I know, it was an oversight.
Still haven't found why the lot is buggy.
