Prior to battle had Thunder Maneuver, Fire Maneuver, Light Maneuver statuses active. I engaged Sarama and then used Deploy to have automaton attack, then I used Heady Artifice, then I used Overdrive.

After Overdrive, I used Thunder Maneuver, then Fire Maneuver, then then Light Maneuver. During Overdrive, the chat log kept reporting 1% overload chance. On the fourth Maneuver use, I got "Overload" status, which immediately wore off.

Here are the literal chat log messages AFTER the use of Overdrive:


"Antisense's Thunder Maneuver overload chance is 1%."
"Antisense's Fire Maneuver overload chance is 1%."
"Antisense's Light Maneuver overload chance is 1%."
"Antisense's Thunder Maneuver overload chance is 1%."
"Antisense is overloaded!"
"Antisense is no longer overloaded."

I ran into exactly the same problem, but when I was killing Shiva VD. Also using Fire, Thunder, Light. But my overload happened right after Fire Maneuver while Overdrive was active. First time I've ever overloaded during Overdrive.
