Set up a hunting portal, went in and came back out, "suffocated in a wall"
Spawned with death compass, compass pointed to portal, Journeymap marker shows death under the portal.
Dug under portal, no grave there. Lost all my stuff.
Spawn under portal instead of next to portal
Change graves to replace blocks if required, have lost full inventory a number of times due to grave based bugs.
As in Issue/Bug
Lost all my items. Died.

I am also experiencing this however my grave is not lost - just misplaced. These are my observations
Most (not all - 6 our of 8 so far) times I return from the hunting dimension I suffocate in a wall.
When I spawn correctly i do so at the portal
My grave is left underground somewhere (I think the first free air block downwards) but not always the exact spot the death compass shows. once it was on the surface.
Overworld Portal is at Y=70
Dimension portal is at Y=64
I just confirmed that I spawn at Y=64
Screenshot: Cobble block is where i spawned last time

Im glad you posted this... I just went back and found my grave 40 blocks away down a cliff in a little alcove.
So weird.
Update: I dug out the area at the cobble block in my screenshot to Y=64 and I consistently spawn in the same place, at that block, and no longer suffocate as there is no stone there any more.
After some more experimentation it seems that if you go to the portal correctly or to the other location (which I guess might be x/y/z from the portal in the other dimension) is dependent on if you are standing fully in the portal or not
I have also now observed incorrect placement travelling the other way (overworld to dimension). I spawned mid air at about the same but opposite displacement than dimension to overworld
This happend also for me, but when I spawned in the ground, all my Items spilled ontop of the blocks, no grave.
I had this same issue as well. When returning from the hunting dimension to the overworld, I spawned about 5-6 blocks underground and about 5-6 block away from the portal (sorry, don't have exact coordinates). I was able to break a couple of blocks quickly and throw down a torch so I didn't die, so I cant comment on losing the grave.
This happened to me also. Except it was going to the Betweenlands. The "death" was in the middle of the swamp, so I have no idea how to locate my gear. I'm assuming it's gone. Interesting thing is, the death spawn was about 50 blocks from where I was actually warping in.

Thanks Darkhax, appreciate the help
This seems to also happen with The Beneath portal.
