I had a stack of red concrete, some ender pearls and some other things. I was fishing and came back to my house to empty my inventory and opened my chest that it was full but now it had half of my things. I never used the red concrete yet & I definitely had because i used a iron pickaxe to mine It also had a bucket of lava.
