I've noticed this more and more over the course of the last couple of weeks.  At this time I don't have a specific save file to go off or anything to really create a bug report at this time.  It should be reproducible as we've seen this in both games created after 1.8.  Everytime the other human player has submitted crash reports via the new tool.  Specific steps although doesn't happen every time are as follows...

• One player is doing random things while on their turn.
• Player two attacks/pirate/AI/anomaly 
• Player two wins however, takes on damage.
• Player two shows one set of hit points remaining
• Player one shows different outcome with different hit points/rewards given (scavenged ship).
• Game crashes either immediately or at next turn.

Upon this happening on our next session I'll create a ticket if issue is not seen on Stardock's part by then and, issue is reproduced.  Over the last couple of weeks we've noticed this 2-4 times.
