I can only recommend that people don't get attached to their creations it is just setting yourself up for disappointment. Usually devs will announce when its "safe" to start getting serious on your game because future updates won't brick previous.

I'm not sure if you read the thread fully. I just wanted to know if there was a change in how the world generated at any point.
