Playing on 9.0.2, when I started to burn wood in a Gas Grill for Charcoal, I ran into this error:
2023-08-15T12:27:29 208.082 ERR [XUi] Error while updating window group 'workstation_cntGasGrillOpen': 2023-08-15T12:27:29 208.082 EXC Object reference not set to an instance of an object at ImprovedHordes.Core.World.Event.WorldEventReporter+AIDirectorChunkEventComponent_NotifyEvent_Patch.Postfix (AIDirectorChunkEvent _chunkEvent) [0x00045] in <f3df1dba03e14536a032e6cdeaed5c4b>:0 at (wrapper dynamic-method) AIDirectorChunkEventComponent.DMD<AIDirectorChunkEventComponent::NotifyEvent>(AIDirectorChunkEventComponent,AIDirectorChunkEvent) at AIDirector.NotifyActivity (EnumAIDirectorChunkEvent type, Vector3i position, System.Single value, System.Single _duration) [0x00039] in <d7dcfa4979674f179c13273f8b30b551>:0 at TileEntity.emitHeatMapEvent (World world, EnumAIDirectorChunkEvent eventType) [0x00046] in <d7dcfa4979674f179c13273f8b30b551>:0 at (wrapper dynamic-method) TileEntityWorkstation.DMD<TileEntityWorkstation::HandleFuel>(TileEntityWorkstation,World,single) at (wrapper dynamic-method) TileEntityWorkstation.DMD<TileEntityWorkstation::UpdateTick>(TileEntityWorkstation,World) at (wrapper dynamic-method) XUiC_WorkstationWindowGroup.DMD<XUiC_WorkstationWindowGroup::Update>(XUiC_WorkstationWindowGroup,single) at XUi.OnUpdateDeltaTime (System.Single updateDeltaTime) [0x00131] in <d7dcfa4979674f179c13273f8b30b551>:0 UnityEngine.StackTraceUtility:ExtractStringFromException(Object) Log:Exception(Exception) XUi:OnUpdateDeltaTime(Single) XUiUpdater:Update() XUiUpdateHelper:LateUpdate()
This keeps looping forever. If I quit and restart the game, I instantly start getting the NullReferenceException in a slower loop again, but apart from that, the game seems to run normally. When I open the Gas Grill GUI, the quoted error again occurs in a very fast loop.
Edit: I managed to destroy the Gas Grill, which also eliminated the error. But now I realize that my save must be corrupted somehow. Whenever any workstation contains any produced item, the "NullReferenceException: Object reference not set to an instance of an object" comes back. ☹️
Also getting this:

Edit 2: So I realized this has to do with the Improved Hordes mod and copied the latest beta 2.0.0-beta.4 over the version bundled with Ravenhearst. This seems to fix it for good.
