Thank you for the answer. The only thing I didn’t try was “try to generate the visual studio files again with the editor closed”, how can I do that?
I don’t think it will fix, though. It appears my blueprints are “infected” with some sort of plague.
And yes, I have made many refactors on my project. Renames, reparentings… I really hope one day UE4 will be more “refactorable”… today, it’s a real pain. Everytime I do that, I have to enter the jungle and hunt the bugs that UE4 spreads over the way…
