Hi, I’m having a replication issue in UE5 and I’m stuck for two days. This used to work in my older systems but now it doesn’t. ### Setup - I have a **Character**. - Inside the Character, I have a **default Blueprint Actor Component** called `CraftingComponent`. - The component has: - The Character: Inside the component: - I call a **RunOnServer** event. - On the server, I **SpawnActor** (Building actor). - The spawned actor: Immediately after spawning, I: - Set a variable inside the component: ### The Problem On the client: If I get the Character → Get CraftingComponent → check that replicated variable, It is always **NULL / Not Valid**. However: - The spawned building actor is visible on the client. - So actor replication clearly works. - But the replicated reference inside the component does not update. ### Additional Info - The component is a default component (not dynamically added). - Component Replicates is enabled. - The variable is set on the server. - I also tried: Still the variable is NULL on client. ### Question Is there any known limitation or special requirement for: Replicated actor references inside replicated Actor Components (attached to a Character)? Is there something specific required to make component-level replicated variables sync correctly? Because: - Actor replication works. - But component variable replication does not. Any help would be appreciated. ---

so just to clarify the variable itself must be Replicated `(BP_Master_M) and since thats an actor that Actor must also be replicated.` if you still have issues it may be a Relevance thing (ie only relevant to owner or out of net range) but i doubt thats the issue ---

yes the variable is replicated, actor is replicated too ---

you’ll have to post a screenshot but to be clear i mean the variable actor must be replicated ---

also keep in mind you’re only setting the variable on the one pawn. it may be the same issue in your other thread where other players wont have that variable set. if you want it global, spawn and save it on the GameState ---

ok well you definitely dont need a MC, just set it to replicated/repnotify if you need callbacks and only on server, so show that code ---

try show the full code, but you only need notify if you need, well the client to know. its worth learning this but incidentally if its local client preview only do you need replicated at all? ---

its worth breakpointing or at least printing your fail paths (ie cast fail or isvalid) also you AC MasterBuilding doesnt have the replication dots? and where is all this code? Character? ---

first function is in a replicated actor component, the gate function is calling from the character. first function is never works with the client. there was some prints on it but i disabled it before i sent the screenshot to you. in server it is valid while spawning it. after that, i am trying o reach the variable because i want to turn it. it says it is invalid ---

im not in editor right now but im pretty sure AC\_MasterBuilding should have the replication dots if its enabled so that may be the issue. possibility 2 is replication takes time, what calls the Character event? its possible its invalid for one tick and then valid a second later but you’ve missed it ---

Should I maybe focus on figuring out why things that used to work before are not working now? Some of these systems that stopped working were already ready-made plugins. Everything was supposed to work out of the box. How can it be just a coincidence that the crafting system, the inventory, and the weapon system all broke at the same time? ---

well you said it was singleplayer before? so not too unusual. maybe start with something simple to test, just replicate a string and print it [Next page](https://forums.unrealengine.com/t/replicated-actor-reference-inside-replicated-character-component-is-always-null-on-client/2703100.md?page=2)
