I died because of a cactus with a full inventory.
I'm close to my respawn point (bed).
After I respawned, all my inventory was gone.
I destroyed the cactus to check if the items are "in" the cactus somehow. But nothing there !
I can reproduce this error (or is it one ?)
Couldn't find a similar problem.
Peace & regards
Cactus blocks destroy dropped items... don't die around them. 😉
