Client crashes when trying to send replicated actor reference to server.

Hello everybody.

I have problem with Unreal crashing for client when I try to send event from client to server. One of the parameters is a reference to replicated child actor named ComputerActor. Main actor, child actor component and ComputerActor itself are all replicated and spawned during gameplay. It doesn’t crash everytime but only when clicking on Computers named Computer_GEN_VARIABLE_ComputerActor_C_CAT_710 in my case (crash message is from my coworker)

Replicating object references | Unreal Engine Documentation - according to this I should be fine because actor is replicated, right?

Crash message:

Assertion failed: NetGUID.IsDynamic() [File:XXX/UnrealEngine-4.27/Engine/Source/Runtime/Engine/Private/PackageMapClient.cpp] [Line: 2106] Non-stably named object Computer_Actor_C /Game/MM/Rooms/CMB.CMB:PersistentLevel.Computer_GEN_VARIABLE_ComputerActor_C_CAT_728 has static NetGUID [767].

Anyone has any idea what can be going on? Thank you for your time.
