Saves, updates and Demo progress
Quick answer
System-heavy Early Access updates may require save wipes. This conditional warning does not mean every patch wipes a run, and does not establish Demo-to-Early-Access save compatibility.

Official Early Access FAQ, checked November 1, 2026. Exact save directory remains unverified.
Keep products and versions distinct
The paid game and Demo are separate Steam apps. Before opening an old world after an update, note which product created it and the build that last loaded it. Do not overwrite your only usable save while experimenting with compatibility.
What the official warning says
The Early Access FAQ warns about possible wipes when major systems change. It gives no universal import procedure or promise that all old worlds receive every new feature. Check the relevant patch announcement before investing in a long run across a major update.
Backups and location
No exact current save directory or tested restore process is established here. Use a verified platform backup or identified save files; do not copy a guessed folder and assume the world is protected.
