Yesterday, me and BlueStar5 were making a tnt cannon somewhere in survival, so then, I logged off and slept, today, I joined, but couldn't login for a reason, so I left. After waiting some seconds, I rejoined and saw a zombie spawner near me with zombies, so they killed me, but I didn't see that, so I also logged off. After waiting some minutes, I rejoined and saw that I died and lost my stuff, this is not the first time it happens, and btw, it was in survival. Please, is there any way I can have my stuff back because I keep dying like that and loosing my stuff.
My stuff:
-57 redstone repeaters.
-64 cobblestone.
-50 redstone or 55, I don't remember.
-2 Diamonds blocks.
-1 Lever.
-1 Water bucket.
-1 iron sword.
-16 Ender pearls.
-1 Iron Helmet
Thanks in advance.
