I have a set of players spawned on the server and replicated on the clients, each client controls one of the characters, so a typical multiplayer setup.
Now, when one client does a certain mouse movement, the character turns around and faces the other way. This works great on the server, but then seems to work randomly on the clients, as it only works about 50% of the time and not on a pattern that I can discern.
The actual character BP’s code is pretty simple. It always gets called when it needs to be (checked by a simple print) but the actor rotation somehow doesn’t always do its thing.
