Fix

The save issues were related to the rollback feature when it was enabled.

All hotfix files have been added to the posts with links, and the online versions have been updated as well.
However, if your save was already broken before, this fix will not help.

Version 27 is also coming soon, and it will include a major content expansion. I've been working on it this whole time. This update will also focus on immersion, adding new gameplay mechanics and a wide range of ways to play through the content.
