i didn't think anything of it at first but here goes
i was in lfr for the first time and we did kargath and i stayed afk at kargath for couple of mins while everyone else moved to the butcher, me doing the raid for the first time didn't know the path to the boss so i kept dying to adds while trying to find my way, meanwhile the rest of the raid was doing the butcher
i finally realised i was supposed to jump down instead of walking a path full of mobs when they killed the boss, at the moment boss got killed i was still on the path where the mobs were and i didn't get the butcher lock, after i finished the raid and left i received loot from butcher in the mail from postmaster
now i don't remember if i was a ghost or not when they killed the butcher but i didn't get saved on the boss itself and i received loot from it
