Projectile Spawn replicated somtime not working on Multiplay

Hello.

I’m using listen server.

Press the button to fire the bullet(Spawn Actor).

The call from the client to the server is done normally.
but Sometimes clients that themselves are not spawn.
Not at all. no work Sometime…. :frowning:
but hit event is run in client(No bullet in Client & run Hit event for server->client),.

Does anybody know about this problem?

plz help.
thanks.
