You died and your tombstone was not there? Do you play alone or with people? Can someone loot your corpse if they are playing while you are offline? I play solo, locally. My game pauses when I log out. I log back in and everything is the same as when I left. I am an experienced MMO player tho. Online games usually stay alive even when you are not logged in right. I assume the world keeps going if you play on a multiplayer setting in Valheim as well, no? Could it be someone took your stuff? I am genuinely concerned about this, because if I were to die and lose my stuff now by a disappearing tombstone, I'd literally lose like 30+ hours of gameplay and it would likely break my seed since certain resources were super limited so far...
