Can't complete Beyond The Grave

I just defeated krolton during the last bit of Beyond The Grave, but my inventory was full, so i did not recieve kroltons remains as i was suppost to. I was teleported out the room too, so had no chance to pick it up if it dropped on the ground. /fixquest does nothing, as im guessing the remains aren't a quest item. What do i do? It won't allow me to finish the quest without the remains.

 

Redo the quest steps and get to Krolton's arena again

Alternatively I think there is a skip near the entrance to Krolton's cave, it's like a hole with smoke or something that you can use to directly tp to Krolton's battle
