Problem: There is an element in the Widget, it will perform the drag-and-drop this widget with the mouse. When you start the game in the editor, everything works perfectly, but if you prepare(cook) the game, the item disappears.
Sometimes, when I continue work on the project the next day, I have to re add this Object to the Widget, as it is missing…
I duplicate it in the object Browser, renamed it, changed it, the old removed, but the problem remained the same.
My initial thoughts on your post would be that you have a circular reference issue. However, I have a few questions that will help narrow down what issue it is that you are experiencing.
Quick questions:
Can you produce this issue in a clean project?
If so, could you provide a detailed list of steps to reproduce this issue on our end?
Could you provide screen shots of any other blueprints/widgets/settings that may be involved with this issue?
Could you use the reference viewer to check for possible circular references?
We have not heard back from you in a few days, so we are marking this post as Resolved for tracking purposes. If you are still experiencing the issue you reported, please respond to this message with additional information and we will follow up.
