I haven't been able to reproduce an increased turn count so perhaps there is no bug, but it seems like the enemies zip toward you very fast after reloading from the automatic menu.
Reloading increases the energy cost of the attack by 1000, and monster movement isn't shown until after you reload, so some double moves are to be expected. Didn't see anything out of the ordinary (i.e. more than two moves from monsters with the same speed) when testing this.
