Object reference not set to an instance of an object

[AH64_Jimbo]

I'm experiencing a similar problem, but in the vanilla game, not Darkness Falls;

 

After completing Tier 1 quests, and moving up to Tier 2 quests, talking to Trader Bob will sometimes throw an error when trying to get a new Tier 2 quest.

 

Here is the error when I try to talk to Trader Bob:

2023-02-03T11:02:58 529.609 ERR [XUi] Error while updating window group 'radial':
2023-02-03T11:02:58 529.613 EXC Object reference not set to an instance of an object.

 

A bit of background:

- Running Alpha 20.6

- This is for a modified vanilla-generated map

- No Mods running apart from MapToolz for map editing

- This instance of Trader Bob is one that I have placed (not generated by the RWG) as part of a new 'town' (Really an airport)

-  All other Prefabs in this 'town' have also been placed by me, including RWG tiles, parts and quest-able POIs

- Some of these Prefabs have been created by me, including nine quest-able POIs; Two of which are Tier 1, and Two of which are Tier 2

- The rest of the placed Prefabs are all Funpimps generated, from the Prefab library

- I was able to successfully complete quests on my player-made Tier 1 POI's via Bob

- Some Tier 2 POIs worked just fine, too, before Bob throws an error

- Thus far I have been unable to test Tier 3+ POIs for this 'town' on this map

- Playtesting my player-made POI's in the Level/Prefab editor was completed successfully for all of my POI's

- I have tried 3 separate playthroughs, each with a new save; I always encounter the same error at some point when getting Tier 2 quests from this player-placed instance of Trader Bob

- Other RWG-placed trader Bobs as well as other traders in other towns on the map seem to work just fine

 

Conclusion:

There may be one or more Tier 2 POI's (either mine or the Funpimps) that I have placed in the world that are incomplete or have errors when Trader Bob tries to populate a list of quests. 

Perhaps in Darkness Falls, a non-Funpimps created POIs may be causing a similar issue. Though, this is just a guess.

 

I would really like to hear more insight that you all may have. 

 

FYI here is a more complete excerpt of the Error from the logs;
