Summary0021564: Problems with reconquest seeding
Description9/3/2019 8:18:03 PM Hit debugCode 30 exception System.Exception: guardPostBag is null for Brand
  at Arcen.AIW2.External.AIDefensePlacer_Default.StartReconquestDefenseSeeding (Arcen.AIW2.Core.ArcenSimContext Context, Arcen.AIW2.Core.Planet ThisPlanet, Arcen.AIW2.Core.Faction faction) [0x000f4] in <5880ab743172483c94406afdb82c323d>:0 in StartReconquestDefenseSeeding

The code is
                    debugCode = 30;
                    PlanetFaction pFaction = ThisPlanet.GetPlanetFactionForFaction( faction );
                    ArcenRandomDrawBag<GameEntityTypeData> guardPostBag = null;
                    if ( pFaction.ShipGroup_GuardPosts != null )
                        guardPostBag = pFaction.ShipGroup_GuardPosts.DrawBag;
...
                    if ( guardPostBag == null )
                    {
                        //Having an empty guardPostBag is okay, but I don't believe it should be null
                        //if it is okay to be null then we can just change the below
                        //if ( guardPostBag.GetHasItems() ) to include a check for guardPostBag != null
                        throw new Exception("guardPostBag is null for " + ThisPlanet.Name);
                    }

My understanding is that the guardPostBag is set in
        #region DefinePlanetFactionDefenseTypesIfNeeded
        public static void DefinePlanetFactionDefenseTypesIfNeeded( ArcenSimContext Context, Planet ThisPlanet, Faction faction )
...
            if ( pFaction.ShipGroup_GuardPosts == null )
            {
                if ( ThisPlanet.PopulationType == PlanetPopulationType.AIHomeworld )
                    pFaction.ShipGroup_GuardPosts = reinforcementBudgetItem.DireGuardPostAIShipGroup.DrawBag.PickRandomItemAndReplace( Context.RandomToUse );
                if ( pFaction.ShipGroup_GuardPosts == null || !pFaction.ShipGroup_GuardPosts.DrawBag.GetHasItems() )
                    pFaction.ShipGroup_GuardPosts = reinforcementBudgetItem.GuardPostAIShipGroup.DrawBag.PickRandomItemAndReplace( Context.RandomToUse );
            }

Thanks!

* Some extra code has been put in place to make it so that if for some reason during reconquest of a planet there are no guard post types already assigned to the planet, the AI can now figure out AI types.
** Most likely the reason this was happening before is that it wasn't an AI planet at the start of the game, and so it belatedly needed to find the guard post and/or guardian types.
** At the moment this is completely untested, but it should work.
