Hi ionutt93,
We’re going to need to see more information to figure out what might be happening here, I think. Which Actors aren’t replicating, Characters? Do they not replicate on Client or Server, or both? You mention that they replicate as expected when map is open and you Play in Editor with clients set to 2; when does this not happen? A packaged project?
If you can take some screenshots of your Blueprint Graph setups, including your widgets, that you’re using, or if you’re able to tell me which parts of Multiplayer Shootout project you’re NOT using, we might be able to see what’s going on. Thanks!
