A user by the name of Thaddalt reported a problem in the Discord server's tech help channel. They encountered an untargetable NPC which forcibly teleported them.
Correct GUID is "211735054"
Since he couldn't target the NPC, he attempted .npc undo, which under normal circumstances helps with this. However, when he used the command it gave this error:
As the error text shows, it attempted to delete an npc with a completely wrong GUID. I believe this is an error in the command, as using .npc delete 211735054 worked correctly and resolved his problem.
I'm not sure if this happens to others, or if it's an issue isolated to this npc, but it is definitely and unintended result.
If anyone can reproduce this with other NPCs, please post it below, as it may help Dr3 locate the problem.
