The problem occurs when trying to join a friends world. Sometimes there is no issue but other times it is impossible for one or MORE friends to join a host friend's world. We was hoping this would be patched in the latest update on PS4. At the moment all we can do is reload the world but even that does not always work. This issue is definitely not a connection issue as we have tested it with many people at many different times. When we eventually spawn (if we are lucky) there is no lag or frame rate drop and so is an example of why this is not a connection problem but a bug in the system. It would be great if this could be resolved and we could continue playing.
