UE5 EA2. Issue still presents. Quite annoying.
I’m sorry for reanimating this thread. I’m having the same issue from time to time and I found some steps to reproduce it.
I have a Master Blueprint, child classes of this Master blueprint and some actors that use some of these child classes as child actors.
When in the Master Blurprint I change a value and then go ctrl Z for undo and recompile the master blueprint the child actors duplicate and become orphans. Really bad is it when I “draw” a value slider and undo it because then I have a lot of duplicates.
I hope this help to reproduce and fix this issue.
My workaround: Since only the editor has problems with child actors and not the game at runtime, I create the Child Actors on BeginPlay. To still be able to see them in the editor, I use the static mesh of the actor as a dummy, which also provides the transformation for the child actor when I create it.
Still happens in 5.1!
Don’t edit BP while with the level open, this cause TONS of bugs.
Also happening in 5.1 for me. Very difficult to reproduce it. Seems to pop up when you let your guard down.
