With regards to this (Won’t Fix) issue would it at least be possible to add a clear warning when reliable multicast RPCs are being dropped? I spent a considerable amount of time trying to track down why my RPCs weren’t arrived on a join-in-progress client. ---

Hey TheBunyip, I’ve reopened the issue for investigation, and you can keep track of the status of it using the link below: > **[The Unreal Engine Issues and Bug Tracker](https://issues.unrealengine.com/issue/UE-24772)** > > Welcome to the Unreal Engine Issue and Bug Tracker. You can check the status of an issue and search for existing bugs. See latest bug fixes too. As far as adding a warning, this is not something that I’d think we’d implement because it is not expected for the reliable RPCs to be dropped. Have a great day ---

This is still an issue in 2024. Why not add a warning? Reliable RPCs being dropped when it’s not expected is IMO exactly when you should be printing a warning. It took several hours of debugging for me to eliminate other possibilities and find this thread & issue - a warning would have prevented that. ---

8 years later… This is fascinating. And another bullet item for why I may need to consider another engine for my multiplayer shooter.
