Re: The sims 4 roommate issues
@PinkyCustomWorld Pets count as regular household members when it comes to having enough beds to advertise for roommates. So with your Sim, the ghost cat, and two roommates that's four beds. A double bed will still only count as one bed and pet beds do not count at all for something like this. You'll need to add one more regular bed (at least temporarily) somewhere on your lot to get a third roommate. You should be able to delete one of the beds after the third roommate moves in.
What I usually do in a case like this is make a small non-access basement under my house and put a cheap bed in there. It will still count towards the required number of beds in my Sim's house to allow me to add roommates, even though it's in a place where no one can use it. That's just how I do it, you can put that extra bed anywhere on your lot & it will still count.
Btw- I'm curious to hear if your roommates use the kitchenettes you made for them or if they eat from your regular kitchen or even bring in food from other lots. Please let us know how that works out for you.
