Obviously no permission.
who the hell are you? the freaking map police?,i look for the authors name before i port these maps, i started to port another map, sent the files to the author,who posted it without saying anything about the work i did,and you all praise them.
and i am an adult,i do not need permission to do anything.
the DEAD grass was in the original map,so its in this map,you dont like it,dont download it or play it.
wheres your port?
