The game is crashing when I hit "cancel" at the start of battle. I know what needs to be fixed but I

I'm using Victor Engine ATB with Symphony side battle.

The problem is that VE ATB removes the "Fight Escape" from the start of the battle. So if I hit the cancel button, the game crashes with this:

Script 'Game_Actor' line 692: NoMethodError occurred.

undefined method '<=' for nil:NilClass

Here is the script that is causing the error:

 #--------------------------------------------------------------------------
  # * To Previous Command Input
  #--------------------------------------------------------------------------
  def prior_command
    return false if @action_input_index <= 0
    @action_input_index -= 1
    return true
  end

Basically the game is trying to go back to a previous command that doesn't exist, so it goes nuts.

I was thinking if there was a way to check to see if @action_input_index was not assigned a value, to either ignore it or set it at some value that isn't causing the game to crash.

If anyone has any ideas on how to fix this, I would be very grateful. I love using these two scripts together, they fit my needs perfectly. I can't find another good ATB script either, so I'm stuck trying to get VE ATB working.

Try changing this:

to this:
If that doesn't work, add a link to the full script, please.

If I could hug you right now, I would!

Thanks so much! Works like a charm.
