    Hello,

    for me the OnClick event does not fire at all if I have a DOTween animation attached to a parent game object and not even the button game object. This does not happen every time but maybe once i four times.

    Best,
    Andreas

    I have the same problem. Actually luckily for me it is not a problem yet but I can confirm. Every onclick action gets called 3 times.

    OnClick() called function running as many times as there are actions in the list.
    Version 2017.1.2f1

    I can confirm exactly what Daimas described in Unity 2017.1.1p4

    It makes both 20171.1p2 and 2017.1.1p3 completely unusable. How this bugs passes review? It's insane.

    Actually OnClick is calling exponentially, if there are 3 actions it gets called 9 nines and so on...

    This happens only on projects that were updated.

    With a fresh project that does not happens.

    Please resolve this issue as the VR and IOS fixes are really important, especially on version p3.

    For me, OnClick() is fired as many times as there are actions in the list. If you just put one event on the button it works fine, if you put two actions each one is called twice, if you put three actions each one is called three times, and so on.

    This makes version 2017.1.1p2 completely unusable.
