Re: [ARCHIVED] Sim uses a different computer to the one they are told to use
I had this issue too, but I haven't seen it happen in my current save (but got a new computer and thus a fresh install somewhere in the meantime).
It may still happen in the save it used to happen in, but I haven't played that one in a while (stuck refurbishing the Science lab - which I need to get done but haven't really felt like doing).
Anyway, what I wanted to say is (since no one really mentioned it yet), there is a simple work around for this issue (which has always worked, even before the ability to lock doors). You simply queue the action to sit on the chair that's 'attached' to the desk with the computer you want to use. Once the Sim sits down there click the computer and select the desired action, your Sim will do so on the computer you selected. I think you can also select the interaction with the computer while your Sim is on their way to the chair, but can't be entirely sure.
Hope this helps 🙂
