It’s the bug that makes some mobs fall through the terrain and then subsequently teleport to the map origin coordinate.
From what I’ve seen so far, Funcom has been having difficulties pinpointing the root cause of the bug, so they added special debugging logic to the game to gather more useful information. Although DvntTears knows this, he might not understand that getting enough useful information on a heisenbug like this one usually takes an unfortunate amount of time.
