ok i know bliz just allowed 13 tile "points" instead of 12, and some editors allow many more. can someone tell me why blizzard wants to keep the limit so small? do too many lag the game or something?
All of you are wrong :P It exists because the header for the map only contains a limited number of spaces for tileset information. If it goes over, bad thigns happen. Why they picked 12 or 13, however, is something only they would know.
