I was about to post regarding this issue as well. As I've read on steam forum progress from the last playtest (which is the current one) will be saved and will carry over. Now i have following questions - does it save progress for those that decide to buy game in later date after full release? And another one, if someone has made some progress during last beta but decides to play on PC Xbox game pass is it possible to carry progress from version used on steam (I assume not but i'd like to get confirmation)?
Thank you for response and best regards
