It also look like this occurs for some (but not all) of the other quick scenarios.

I can't reproduce this for any of the quick start scenarios. Are you on the most recent code?

 Hey Chris, see 0022834 for what looks like a variant of this. Here's what my code does for the FleetMembership serialize/deserialize

                GameEntityTypeDataTable.Instance.SerializeByInternalName( this.UnitTypeToBuild, Buffer );
                GameEntityTypeDataTable.Instance.SerializeByInternalName( this.BaseUnitType, Buffer );
                Buffer.AddItem ( this.BuildPoints );

and then

                if ( Buffer.FromGameVersion.GetGreaterThanOrEqualTo( 1, 333 ) ) //ViralShredders
                {
                    typeData = GameEntityTypeDataTable.Instance.DeserializeByInternalName( Buffer, "FleetMemDeser" );
                    result.UnitTypeToBuild = typeData;
                    typeData = GameEntityTypeDataTable.Instance.DeserializeByInternalName( Buffer, "FleetMemDeser" );
                    result.BaseUnitType = typeData;
                    result.BuildPoints = Buffer.ReadInt32();
                }

Do you see anything wrong with this?

The actual bug wasn't in deserialization direct, it was in the constructor:

at Arcen.AIW2.Core.Fleet+Membership..ctor

Basically, a null type is being passed in, which is fine for deserialization as it gets that data later, but it doesn't know that so wasn't checking for a null. Fixed!

Wow! I see a new update came out moments ago. Can confirm I don't see the error anymore.

Thanks for the fix.
