I am sorry you are having issues with your UI. But I did not create the Unreal Engine. You are experiencing bugs because you are creating circular dependecies in your logic.
You need to understand what is happening before you start pointing fingers. I try and be extremely helpful and informative but there is only so much I can do to help with changes people have made to the logic.
I understand your frustration and wanting to blame me. but perhaps the ARPGIS is not right for you. Insulting me and my work is not going to make me want to go out of my way to continue to provide hours of free support for issues you are experiencing with changes to your own project.
If you would like to ask Epic for a refund I would be happy to tell them to approve it. The last thing I want is 1 unhappy customer.
