Hi all,
For this update I decided to focus all of my time on code, doing things I've needed to do for *years* so no new decorations today, but hopefully you'll enjoy this update all the same for the many new features and improvements that have been made!
- Autosave & Quicksave
Your building progress can now be automatically saved as you play. Autosaves don't overwrite your manually created saves, instead there are three rotating slots dedicated to it. You can choose how frequently it happens in the options menu, or disable it if you prefer.
Additionally, you can now press a key (F5 by default) to trigger a save. 
- Large world optimisation
Several low level aspects of the game's code have been upgraded to improve the experience for players building gigantic worlds with a large number of decorations:
