You could try rebuilding from scratch. The easiest way to do that is to go to (File->Package Project->Zip Up Project) in the editor and create a zip of your project. Then extract the zip and build that copy. If you still have the problem then you will need to provide more information. There’s no way to tell what the problem could be from your description.
One note: when you build from scratch, try to go back to the last version of your project that you know worked before. Don’t use any version since you messed with it (i.e. the one where you tried creating new actors and components).
I create an actor on server side from the actor component. This actor who must also replicate to clients, and he did it successfully.
After updating a lot of content, it stopped working. The created actors on the server are no longer displayed on the clients.
Is it possible to fix it without creating a new project?
PS1. all actors that are created from the actor component are no longer replicated.
PS2. creation of new actors and new actor components did not solve the problem
