Server can't see how client spawn projectile

So I’ve got Child Actor (MasterWeapon) in my character blueprint. In MasterWeapon blueprint I’ve got a function “FireBullet”, which is spawn projectile.

In Event Graph I’ve got simple multicast event, which execute function “FireBullet”.

Going to my character blueprint (CH_DevPlayer), where I’m casting to my Child Actor for event “Shoot”, when InputAction Fire is performed.

As a result: Server shooting? Client can see it. | Client shooting? Server can’t see it. What’s the problem?
