Guild Wars 2

I know theres been a lot of reports of creatures and therefore DEs that get bugged out. I think I figured out the issue. GW2 has a built in anti-exploit feature with creatures that makes them invaluable to attacks when the creature cannot attack the players. This mostly triggers when characters are on platforms creatures can’t reach or visa versa. It appears that this anti-exploit feature is what is causing the majority of creatures to become bugged. It seems to me that the game does a check any time a creature moves in the Z plane and applies invulnerability to the creature when its out of range of the player.

“Easy fix” – move creatures away from cliffs/areas where there is not-free movement in the z plane. I had a creature bug out on me when moving in and out of water. The creature could do the same, but I killed it in the “middle” bugging it out and preventing me from completing the skill challenge (and anyone else who wants to do it)

“Easy fix 2” Despawn and respawn creatures else where when invulnerability last more than 10seconds. Annoying for boss battles

Stop gap before fix – Hire some GMs with the power to force move or kill creatures. Give them a gem stipend for their time or something.
