Hello, i have my city which is protected with worldguard and has all the flags to protect it and what not. i have a marketplace of the city in which i have plots that people can buy then ill set it up so they can build on it but when i set it up they cant build on it unless i give that plot specifically build on privledges which would allow anyone to build on it and not the person it's suppose to go to i set it so he would be the owner of the plot but it still did not work until i made it so the plot was able to be built on which makes it so anyone can build on it. how can i make it so only the person who buys the plot can build on that plot
