What am I doing wrong then?
Because I had all the normal codes for the Statue structure and it didn't show up in-game, but then when I deleted the Psychic Tower and then added the Statue for Yuri, then it showed up and worked in-game.

I'd need to see your code in order to determine what is wrong with it.

But the only differences I did to the code was delete the Psychic Tower.

So the Statue wouldn't work if I had the Psychic Tower, but when I deleted the Psychic Tower code then the Statue started to work.
