I have a struct which is used in several classes. Those classes have an array of this struct which array is filled and set up in the class defaults panel.
Every time I modify the struct (like add a new variable there) all the changes I made in the arrays disappear, the structs reset, have only their default values. By now it’s around 50 elements so I really don’t want to redo them every time I need to extend the struct.
I am having the same issue with 4.11. I use structs in my inventory for the display and data of that item. Sometimes, not always, I will add variables to the structs and it will reset the structs in my inventory pickups (actor blueprints) to default values.
I found a hacky workaround:
- Save everything before changing the struct.
- Change the struct.
- Save the struct, and only that.
- Quit the editor. DO NOT save changed blueprint assets! They already lost data.
- Start the editor again, already set up structs should still have their proper values.

Thanks for the solution ZoltanE!
Does Epic know about this bug? I found it in UE 4.13 as well.
I’m not sure if Epic knows about this. Here is the list of BP structs related issues but I haven’t had the time to read it through:
