There's a bug in ARK that sometimes, when you die, or kill something, it just glitches into the ground and falls first into the water, then out of the world.

The Island map gave a pretty good workaround for this bug: placing a second, completely flat ground just above the water level. My feature request is that Valhalla does the same, so if for example a player dies, and the loot glitches into the ground, it could still be saved with the cheat command 'ghost'.
