I keep having glitches.

 I made a house and DL it from my gallery a few years ago and I moved my Sims in the house and I can't put anything in my inventory that's in the house and it keeps saying it's not mine and can't press the H20 to save water. I tried clicking on the door to make it the front door because my other playable family snuck in through the window for some reason instead of knocking on the door like a normal sane person.
