I'm not sure if its intentional or not but dying in other dimensions (at least the AoA ones) can cause your inventory to be deleted and no grave to spawn at the death point. Ive had it happen to me in Haven and other players have said it happened to them too in AoA dimensions.
When you die in another dimension on aoa it will generate a new area once you return. You can get lucky if you keep dying in the same dimension. Your items are there but not in that particular dimension. The waypoint sets itself where you died not the certain dimension.
I'm not sure I understand, we don't have anything. You have a grave that doesn't store your items. Seeing as we are getting off the original topic of the OP's subject, I suggest we stop and move to a PM. PM me if you'd like to continue this conversation.
