**To Reproduce**
I still have not been able to nail down specific reproduction steps as this is one of those bugs that goes away as soon as you try to debug it. The times when this has happened, I was doing a workflow where I was adding/deleting an sk constructor by moving files into and out of the scripts folder and then reloading my project. This may or may not be a factor.

Bắt đầu với SkUEReflectionManager::add_instance_property_to_class() tại skuereflectionmanager.cpp:788, sau đó lần theo sync_all_to_ue() và FSkookumScriptRuntime::OnPreCompile() tại các dòng được báo cáo. Điều tra workflow khởi động editor và tải lại script liên quan đến các constructor Skookum được thêm hoặc xóa; được xem là hoàn tất khi assertion RF_NeedLoad/RF_NeedPostLoad/RF_ClassDefaultObject không còn xảy ra và có một trường hợp hồi quy có thể tái hiện.
