So a lot of the editor buildings that have worked in the past are not solid anymore. Right before a restart they disappear causing you to fall to your death. Some things like stairs, platforms, and ramps you now just fall through them when you try to interact with them. Haven't yet tried this but also have seen others having issues playing together on two different consoles in the same home. My husband and I play every weekend together so I very much hope we can still log in together with the new update.
