Windows Activating Quest results in Not Implemented Exception

I've experienced this bug twice in my current game. Once during my first week when I was attempting to activate for a quest to a POI that I had yet to enter. The second time happened on 2025.07.11 @10:00pm US Central Time.

The bug occurs when you attempt to use the new Quest Marker to start a Quest at the target Point of Interest (POI). The most recent POI that this has occurred at was a completed Judie Witch Fetch and Clear Tier 4. I do not believe my steps will yield consistent reproducible results, but I will add what I did up to the most recent incident. I believe the bug is occurring during the POI refresh step, because, even when it is a POI you had yet to enter, it still refreshes the chunk when you activate the quest. The weird irreproducible issue is that the Judie Witch POI in question was already cleared as a quest once before, so the refresh seems to be inconsistent as well.

I investigated CopyIntoLocal, and it seems that when copying TileEntity from prefab into the world the game checks if there exists a TileEntity already at that coordinates.
If it does, the game calls CopyFrom for existing TileEntity, which does not seem to be sane at all, since it can be an object of a different class.

I guess to repro that you can try to build a TileEntity that does not support CopyFrom (wooden storage box is like that, I think) at a zombie spawn point. Maybe zombie spawn point wont do it, hard to tell which prefab TileEntity it was.
 
I reported this back in 1.0. It can be repro'd if you place storage crates where you know sleepers can spawn. They confirmed it back then, but it seems to have gotten worse in 2.0 as there have been several reports here now with this error.
 
I experienced the same problem and accidentally reported it in a different thread. I was just in a hurry and didn't search for the name of the error that was being spit out... But I did check the known bugs list and every other bugs list and didn't see this so that was kind of concerning... For me the issue happened at working stiff tools.
