One thing Phil did say was that -
The “find a way that something could be saved for the players” makes me think they’re wanting to find a way to get builds moved to private universes… though that might be less a blueprint thing than having a way to copy existing worlds as a whole to them? (I haven’t played with testing so not sure what is possible there on them so far) James did say there were incomplete changes in the update that are causing the delay, that they were struggling to find time to work on… for it to be taking this long, perhaps could be a change of this nature - to play on the safe side for if the time comes SE stops funding, to have a way to migrate builds to private universes in place? So if they go offline or have no choice but to reduce the costs of the servers substantially and remove some of the universe, at least there is some way to keep what we have made?
