the map wasnt copied/pasted, iv had problems in the past of people stealing my work and claiming it as there own, so i try to take mesures to stop that happening again, i simply delete add/subtract brushes from the map before i release it , they dont do anything during a game anyway 
I hope that it will work out for you. My life just does not alow me to stick to one thing anymore. I have had to give up all hobbies, just to keep my place up to standards. And I am also going to bed earlier than I used too. Like I said, I am getting old. 
My heart is still here though.
