Can't interact with npcs

[fallight]

Sorry to bother you but there's a bug about npcmod.When I play 7DtD 2.0 version with the npcmod,sometimes I can't interact with my hired npcs.When I press E on them there's no respond and the console tell me a NullReferenceException happens at 0-SCore/Scripts/Entities/EntityAliveSDX.cs Line: 536.The error usually happens on those npcs who continuously follow me after about 30mins.The problem doesn't effect npcs in my backpack,save/load can temporary solve the problem,and the effected npcs can still move or attack.
Here's the log:

Player.log

My English is really terrible and I wish it won't cause you any trouble.

There are a lot of warnings and errors in the log. I am guessing there is a NPC that is being added that is not properly set up to have quests. I also see some mods that are not being loaded

I also got an error like this when I repaired a building but instead hit an NPC

NullReferenceException: Object reference not set to an instance of an object

I'm sorry for having no reply because I'm trying to find where‘s the bug these days.So I find after 23:59,the bug would happens on those npc who I have talked to.In QuestEventManager.GetQuestList() from origin gamecode,when the date of game changes, the code would try to clear playerQuestData.QuestList.However,the code doesn't except there's npcs with their QuestList is still null,so when the game try to use .Clear() on a null target,the bug happens.Could you consider to fix this bug?As far as I know, there's few npc mods have quests.

I'm sure that's where the bug happens because I make a HarmonyPrefix on it,before the function try to use .Clear(),the Prefix would new a QuestList<> so the function can use .Clear() safely,and then the bug doesn't happen again.
