I was doing some remodeling on my sims house. Added some rooms, put it on a foundation and built a porch. After coming back to live model I notice a visiting sim came through the front of the house and knocked on the back door from inside the house.
ok, No problem I thought, the front door got unset so I click on the door and the only option that comes up is to lock the door, no option to set it as the front door.
I tried deleting the catch files, repair the game, saved the house to my library and put it back. Then I thought this started after I edited the house so I went back to build mode and dropped the foundation back down to the ground. Back to live mode and still no set as front door option so I went and deleted the porch and checked again and I could once again set the front door.
So I thought maybe it was the porch that done, so I figured a foundation with no porch and just add steps. So I put the house back on a foundation and once again I couldn't set a front door.
The only way I can set a front door is if the house has no foundation. If I raise the house the front door goes to being the inside of the back door.
