I currently thought of a workaround: Use the scoreboard manager to assign scores to a player when they complete a tracker or increment the tracker. I’m going to see if this works.
At the very least, the player will feel rewarded for their game time, despite the tracker resetting even with the Save Point Device enabled.
Update: Score isn’t working as well as I intended. seems to reset when you start game again.
Another solution: Use resources (gold, metal, wood, stone as a way to reward players for their incremental progress through trackers and completion of trackers. Resources are persisted nicely.
