I'm having trouble starting an immortal dynasty, because I have pets. I was going to put it in Sunset Valley, but the equestrian center is taking up the lot. I bulldozed it, and it showed as a lot, but when I tried to place my sim in it, the open lot symbol would not show up. I tried bulldozing it again, but then it stopped being a lot all together. I tried to put the largest side lot there in world editor, but it said it wouldn't fit. What's the problem? I've had this problem before trying to place venues, but that may be unrelated.
