When Sim is checking out an apartment, he is not supposed to go inside, only to stand on the doorstep. So I guess it was a bug that he entered.
My sim did that too! He entered the entrance hallway and just stood there thinking.
-the landlord is too pushy. Have you noticed that he's very talkative and stuff and it annoys me when a sim is doing something with the landlord harrasing him.
-The furniture is pretty good methinks although they crammed everything they could in this last Ep to make people buy it.
-the earthy hug gesture looks like a normal, friendly hug to me, nothing special.
