Godmode - Quest Buff Makes Players Invincible And Able To Do Damage (FIXED) (Patreon)

There is a major bug  with the quest "Follow Me" which is offered during the Maldraxxus order hall campaign. If you enter a battleground whilst the invisibility buff (Xennir's Shroud) offered during this  quest is active you will become impossible to target and kill, yet you can still do damage.
