Placing a new lot in a world.

[FrankieShyann]

I am trying to place the bowling alley that I've saved to my library from the Sims 3 University Life world while in edit town, I go back to my home world and try placing the bowling alley, but all the icons disappear (even the empty one's) to where I can't place it anywhere. I've made the lot to a community lot before placing it and made sure the lot was big enough to fit the building's size, but it still disappears, I don't know what to do, any help or explanation as to why the lot icon's would disappear?

I'm not sure. What community setting are you putting it on? So Visitors Allowed, University hangout, etc?

 there may be something on the lot that is making the game "think" the lot is occupied when it isn't like a seed,space rock .wildflower so go to edit town choose your lot then go to build/buy throw some furniture on the lot doesn't matter what chairs,sofa's beds desks then bulldoze the lot then see if you can place the bowling alley
