In case someone have curiosity and want search a rect/region in a deprotected map I made an easy three steps guide to search a rectangle or region.
1.Search the rect you want to find in the map with jass (or any text editor), commonly called gg___rct056 or so or find the function RECT (A,B,C,D) where ABCD are numbers, like the img.
2.place any rect in world editor (with the map opened) and modify the values according to the rect you want to locate. (watch out, the order isn't the same, 2nd and 3rd number are swapped).
3.double click to the rect to see wherever it is
In this example, the rect it's the place where you begin/respawn or load a character in this map.
Hope it helps and if someone have any questions or need help about a step I will try to solve it.
