Ancient Debris

I was bed mining in the nether for ancient debris and I had a couple shulker boxes with me and one was filled with 25 ancient debris. I placed the shulker box down to put more in and my game disconnected from the server and wouldn't let me back on. After restarting my game and console I just waited a few hours and I got back on and the shulker box is gone and it spawned me 100 blocks away from where I was. So long story short I lost 25 ancient debris. I was playing on a realm.
