Fixed in v1.0.336

I finally managed to reproduce this issue, after a lot of tries. Then it took me 5 minutes to fix it, whew :)

from dotween.

I am having a similar issue. I am using DOTween all over my project and I am getting this error with the last version (V 1.0.720) this is the error I am getting

IndexOutOfRangeException: Array index is out of range.
DG.Tweening.Core.TweenManager.RemoveActiveTween (DG.Tweening.Tween t) (at D:/DG/_Develop/__UNITY3_CLASSES/_Holoville/__DOTween/_DOTween.Assembly/DOTween/Core/TweenManager.cs:790)

DG.Tweening.Core.DOTweenComponent.Update () (at D:/DG/_Develop/__UNITY3_CLASSES/_Holoville/__DOTween/_DOTween.Assembly/DOTween/Core/DOTweenComponent.cs:50)

the error pointe me to this line of code:

private void Disappear()
{
_spriteRenderer.DOFade(0, _fadeTime).OnComplete(Deactivate); // <-----
}

I am also getting this error which points me to the DOTween object in the scene

IndexOutOfRangeException: Array index is out of range.

This really shouldn't be happening anymore, damn. Can you paste me the Deactivate method body? There is probably something there.

P.S. note that you can fix this error by using SetTweensCapacity to set the capacity already high enough that it won't need to be changed automatically. But if you can help me identity this issue it would be great.

I'm still getting this.

happened when I reloaded my scene

private void ShowLogos()
{
    logos.SetActive(true);
    logosSpriteRenderer.DOFade(1, 1);
}
