What steps will reproduce the problem? 1. I created 2 classes

[ProtoContract(SkipConstructor = true)] public class BuildConstruct : TimingBase { [ProtoMember(1)] public string name;

public BuildConstruct():base(1)  { }

protected override void Complete()
{
}

}

and

[ProtoContract(SkipConstructor = true)] public class BuildingWithWorkers : TimingBase { [ProtoMember(1)] public GameResources BuildResources { get; protected set; }

public List<Worker> Workers { get; protected set; }

[ProtoMember(2)]
public List<int> WorkerIds { get; protected set; }

public BuildingWithWorkers(float time, List<Worker> workers = null,  GameResources resources = null) : base(time)
{
    if (workers != null)
    {
        Workers = new List<Worker>(workers);
        WorkerIds = new List<int>();
        foreach (Worker worker in workers)
        {
            WorkerIds.Add(worker.CurrentUnit.Id);
        }
    }

    BuildResources = resources;
}

public override void OnRemove(Unit unit)
{
    base.OnRemove(unit);
    foreach (Worker worker in Workers)
    {
        worker.CurrentWork = null;
    }
}


public virtual void Cancel(MacroGameEngine engine)
{
    engine.Resources = engine.Resources += BuildResources;
    CurrentUnit.RemoveStrategy(this);
}


protected override void Complete()
{

}

}

base class UnitStrategyBase

2. Serialize first - InvalidOperationException: Unexpected sub-type:InvalidOperationException: Unexpected sub-type: BuildConstruct ? why, i set this in protoinclude.

3. Serialize second - ok
