First time I tried a game under beta2A, my custom race had been a selected opponent in an earlier game, and I deselected them when starting my first game under 2A. Now, starting my second game under 2A, even though the .customrace file for them still exists, they are not displaying as a selectable race. Do I need to recreate them for the new beta build? An unselected custom race that previously existed was displaying properly.
