Re: Make Sim use one Kitchen at a time?
It could be solved by locking the door for the mom downstairs and upstairs for the daughter. But this would result in them not being able to visit each other.
If you have a door in front of the kitchen you could lock that, but it won't help for the computer. Sims are very weird creatures, they seem to enjoy walking a lot, even when their needs are extremely low...
The kitchen thing is a known bug though, feel free to comment and add a me too:
