Are you sure to have "build" the storage/reserve chamber? I think can be a new function, anyway when i have played, the R ants where in from the initials tutorials mission. I have stopped however, the game is clearly more than less in alpha state, there are maps and replay value but lacks functionality.

Dont happen to me, i installed this version some day ago. You probably dont make the right moves. The instructions are in number here visible on all the site pages.
