Probable exploit, bug either way.

[Aspect of Sorrow]

Box-in exploit capable with "boss" creatures, and any others who interact typically via melee. Player had created about nine throughout the area, which broke pathfinding from the bosses to reach them. The NPC maintains the player name, is not hostile to other NPCs, but sets to hostile with the PC in the area without actually attacking. NPCs are not despawning, and are not 'bumpable'.

How exactly was this done? How does a player create Unknown (At least to me so far) things to block NPC's in?

[matelener]

I think dead bigbies create one.

Perhaps I am mistaken, but I thought it was general policy to not make possible exploits public knowledge, and instead send a PM to QC or the DM team?

[Aspect of Sorrow]

It's not dependable enough to warrant it as being easily repeatable, as the invisible NPCs meander around any PC they decide to stalk, hence "probable" in the title.

I stand corrected, then.
