[QUESTION] Destruction (issue?)

Hello everyone!
I have question related with Shooter Game Example - destruction part.
I put destructible mesh as example into my level, if I running dedicated server with 2 clients (server and client OR client and client) I can destroy it only with weapon launcher, not with gun.
If I entering game without server, clients - mesh can be destroyed by gun. Checked replicates and other things, everything is setup like on launcher.
Do you have any idea what can it be ? I was thinking about projectile but not sure.

Gun with client :

Launcher with client :
