this is because of the most recent bnet patch.
from patch.txt:
- Fixed an exploit where an altered custom map would be seen identical to
the original custom map.
it now sees dota, and dota ai as the exact same map. put the ai in the main folder, or make a folder called AI and put it in, whatever you want.
E/: haha, this also happened when i was teaching my brother how to play.
