I think I get what's happening. Punch and Single Shot are both very quick attacks (5% Windup), and if you were fighting Berserahnas, their attacks are quick too- Bubble Jet in particular is 10% Windup.
The delay's still there- I did some testing with the debug console. The attacks are just coming out before the bars update, too quickly to properly show them until every attack has fired.
EDIT: Ah, geez. That needs an enter, it's supposed to say "in the castle" at the end. That'll be fixed next patch.
