Looks like an error with the triggers. Did you use custom script (JASS) anywhere in your triggers? Did that error occure after you changed something in trigger-section?
no :/ even when i make a new map and try to save it without even touching it just make new and save it cancels the Melee triggers, it just cancels all my triggers when i save :/
I had the same problem , its from the patch ... thats why i have 2 warcraftIII games One game i installed the one that i am using , and the other warcraft game i taked from someone else that was allready installed .
