ArgumentOutOfRangeException when using cooldown decorator

[Awcmon]

I have a behavior tree:



Sometimes, when deploying flares, I get an error:

ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

If I remove the Cooldown decorator, I no longer get that error.

I'm not sure why the bug happens. It seems to happen almost randomly at the Deploy Flares task.

The current code for the Deploy Flares task:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using BehaviorDesigner.Runtime;
using BehaviorDesigner.Runtime.Tasks;

[TaskDescription("Deploy flares.")]
[TaskCategory("Pawn")]

public class DeployFlares : Action
{
private Pawn pawn;
private EnemyController controller;

public override void OnAwake()
{
pawn = GetComponent<Pawn>();
controller = GetComponent<EnemyController>();
}

public override void OnStart()
{

}

public override void OnBehaviorRestart()
{

}

public override TaskStatus OnUpdate()
{
if (!pawn || !controller) { return TaskStatus.Failure; }

pawn.DeployFlare();

if(pawn.FlareBurstProgress > 0)
{
return TaskStatus.Running;
}

return TaskStatus.Success;
}

public override void OnEnd()
{

}
}

This has been fixed in the latest version of Behavior Designer. Try updating and if it still doesn't work can you list the steps to reproduce from a fresh project?

Okay, I updated and it seems to be fixed. Thanks for the incredibly prompt support!
