Game Mechanics: Quillmane corps not opening up

[Udabut]

When farming Quillmane twice our group could not loot the corps:

1) Quillmane was killed at the north spawn point by member of group. Cloak was on corps, I ran up from the Hermit house to lock the corps while he got on alt and ran him over. I could not loot/lock the corps kept saying I “was not close enough to loot”, while I was standing on top of it. Members alt was too late to loot, but I could have used on my main. (no, not looking for a “free cloak”) would just like this looked into so we don’t’ waste our time again.

2) Pet killed Quillmane at Hermit camp. Other member of group that was killing PH’s again could not loot the corps. No idea if there was a cloak on it or not? Again not looking for anything, but would like to have Quillmine looked into on when the corps should open up.

Thanks,
