I'm making my own side in the Warcraft 3 Map Editor, I've so far got a worker, town hall plus four upgrades, the last one acting as a unit, a barracks with two swordsmen, one requiring town hall level 2, an arcane sanctum of sorts selling two spellcasters, one requiring town hall level 2 and the other level 3, a defensive tower, and all the buildings linked properly with realistic requirements. I've made my own map in which I can test this new side-in-making against a Human computer base, but whenever I try to use the build ability on a worker, select a building which trains units - with the exception of the town hall - or try to upgrade my town hall, my game inexplicably crashes. In other words Warcraft 3 closes itself. Anybody know why this keeps happening?
