Ok, sorry for the thread bump but I searched and this is the only relevant thread I could find.
This has happened to me twice today in the Unit Anniversary mission. The first time it was a poison sac drop so I just ignored it. Second time it was the Copper Flecked Geode of Adroitness. My group was there for the kill. Autoloot was working the whole mission for pages etc. I awarded the item to my bard, it went to his window. It wasn't reded out as he was there for the kill. I got the message You are not allowed to loot this item. Copper Flecked Geode of Adroitness.
You may not loot that item from this corpse.
After being frustrated I just clicked the X leave on corpse option.
Then I tried to loot the item the old fashioned way with the normal loot UI...same message.
The rest of my group then tried to loot and got the same message, so no one was able to loot the corpse, all were there for the kill in a locked instance.
I had the item drop earlier and my SK looted it.
The fact that this bug happend on a Venom sack tradeskill Rog item makes me think it has nothing to do with the item off the named.
This seems like an EQ bug, members in the group are running
MQ2Eskay, MQ2Beast, MQ2Rog,
MQ2Shaman, MQ2Berserker, and bard is running /
kissassist. autoloot was turned off so I could assign loot
I have been chain running the missions
/kickp task after an hour and getting a new mission to farm the named. But I was able to loot through the hour of trashing killing for exp and pages so I'm not sure why it would wait for this kill to not let me loot.
