[Error] Error when opponent's PP runs out

[mpvds]

Whenever the opponent trainer runs out of PP an error message pops up when I select an action. (error message shown below) I think the trainer attempts to struggle but is unable to. This happens in both single and double battles. [edit: The trainer does have multiple pokémons so it should also be able to switch when I make the trainer AI at a high enough level. But is still does not change the error]
Also when a wild pokemon should struggle it instead doesn't do anything. it just sits still and will not take an action is this normal programmed behavior in essentials v18? I want the opposing wild pokemon to be able to struggle can I change this.

I do not have any mods installed on this essentials so I think it might actually be a programming bug. Can someone help fix it? I am to new to essentials to understand the code written at all.

I don't have that error in my scripts.

Can you post the code for the the function:

def pbMessageOnRecall(battler)

please?

 

[mpvds]

I found this defenition in Battle_Action_Switching. Is this what you meant?

def pbMessageOnRecall(battler)
if battler.pbOwnedByPlayer?
if battler.hp<=battler.totalhp/4
pbDisplayBrief(_INTL("Good job, {1}! Come back!",battler.name))
elsif battler.hp<=battler.totalhp/2
pbDisplayBrief(_INTL("OK, {1}! Come back!",battler.name))
elsif battler.turnCount>=5
pbDisplayBrief(_INTL("{1}, that's enough! Come back!",battler.name))
elsif battler.turnCount>=2
pbDisplayBrief(_INTL("{1}, come back!",battler.name))
else
pbDisplayBrief(_INTL("{1}, switch out! Come back!",battler.name))
end
else
owner = pbGetOwnerName(b.index)
pbDisplayBrief(_INTL("{1} withdrew {2}!",owner,battler.name))
end
end

If the error occurs with every battler then it might be in whichever code checks for 0 PP in all moves for the active battler.
