Have not been able to figure out why my game keeps crashing. I finally got around to poking in the log and this was the final entry.
[19:24:02.670]  [ERROR] Rocketry II Exception in: (Minion).SparkleStreaker.root.overjoyed.Exit
Steps to Reproduce
Seems to only occur when a duplicant gets the Sparkle status and it expires. Then the game crashes.
This issue has been fixed in either a future version or updated in a previous version.
