I have the same bug
I found the issue
Class - MyDefensiveCombatBlock
Method - public void Flee(bool force = false)
this.m_lastKnownEnemyPosition = new Vector3D?(this.Enemy.WorldMatrix.Translation);
this.m_lastTimeAwayFromTargetFleeWPGenerated = MySession.Static.ElapsedGameTime;
List<MyAutopilotWaypoint> fleeAwayWaypoints = this.GenerateNextFleeAwayWaypoints(this.m_lastKnownEnemyPosition.Value);
The last known position is a nullable, the enemy can be null, but you are not null checking that before you try to generate the next flee waypoints.

Hello, Cameron!
Thank you for writing to us.
We are glad to know that you have found the cause of the issue, but when we attempted to replicate the issue on our end we didn't encounter the same issue. Unfortunately, the shared video appears to be "private", preventing us from viewing it.
So, could you please confirm whether the server where you experienced this issue was modded (with active MODs) or vanilla (without active MODs)? If the server was modded, the problem might have occurred due to the MODs.
Have other players on this server experienced the same issue, or did it occur with you only when using this particular/shared ship?
Please provide us with the complete server and player logs from when this issue occurred. Additionally, could you either attach a screen recording/video of the issue here or adjust the privacy status of the shared video link (keeping the video "unlisted" on YouTube) so that we can review it?
Kind Regards,
Keen Software House: QA Department
