[BUG] duplicating actor remove components -- U4.9

When duplicating actor , most of the time all components like trigger, mesh, light and so on is gone. Variables and macros are intact, but i have to recreate most of components.
I’m not sure if this is the right place to post bugs, but i’m getting a bit desperate.

Could you please report this to AnswerHub? And provide a simple project that demonstrates the issue so that Epic can take a better look.

yeah, i just noticed there is actually a sticky for this. sorry about that.
