Unused Units
Unused units that previously crashed(i.e. Unused Zerg Bldg 5, Protoss Marker) no longer crash. They mostly just create a rock sprite. Unused Terran Bldg has a strange whistle sound when selected and behaves like an add-on (give unit not working).
Found this from the Starcraft beta images, it may be related as the unit wireframe (above HP in game) is nearly identical.
