In 4.15 replication sometimes stops working from server to client

Since upgrading to 4.15 in this project, there are times when replication from server to client stops working. Replicated actors spawned on the server are not visible to clients. However, replication from client to server is working. Example, client 1 calls a server function to spawn an actor. Actor spawns on server, but client can’t see it. The blueprint code has gone unchanged since 4.14, but now stops working. Clearing the intermediate folder and repackaging sometimes causes it to work again.

Hey BlackRang666,

After spending some time looking into it, I haven’t seen this issue occurring in my own networking test project. Could you provide a specific example of when this is occurring? How often is this occurring?

Also, are you able to reproduce the issue in a clean project? If so, can you please provide me with a list of repro steps.

I am marking this topic as resolved for tracking purposes, as we have not heard from you in a few days. If this issue persists, feel free to respond to this thread. For any new issues, please create a new Answerhub topic.

Have a great day

I could not find a way to reliably replicate this issue in a new project. Could I simply give you the project this is occurring in?

Hey BlackRang666,

As a result of neither yourself nor myself being able to reproduce the issue in a clean project, it leads me to believe that the issue is not a bug. Unfortunately, with the idea that this is not a bug and likely an issue with the specific project, we are unable to take further action on this. We do not guarantee support for development questions, and are unable to allocate resources to debugging the project.

However, if you are able to determine the issue and reproduce it in a clean project, feel free to leave a comment to reopen this thread and we can continue to investigate.

Have a great day

Can you give me a list of ‘not a bug’ reasons why an actor set to replicate and spawned server-side would not also appear on the client that I could check for?

The reason I do not believe it is a bug is because neither yourself nor I have been able to replicate the issue. This leads me to believe that there is an issue with the setup in the project that is experiencing the replication problems. As stated, if you can recreate the issue in a clean project and provide us with a list of steps, we can continue to investigate.
