Hungry rock

I have the quest feed a group Mate onnmy screed on a rock my group Mate died on no matter if I'm in a group or if I change dinosaurs.

I was in a group of herbivores with some friends and one of them died with the green foot quest on their dino (the feed a group Mate quest) and after dying we both could see the green foot in the same spot no matter if we changed dinosaurs or if we were in a group

It should of disappeared when they died and left the group
