Watch out, I'm coming

today I was was wondering around and I noticed a pink sheep with a name of "Phil", so I figured there was a base nearby. I dug down, and mined for a few hours. I was about to call myself stupid, and I decided to dig one more block. I couldn't believe my eyes when I had dug into a chest. I opened it, and there was 3 stacks of diamond blocks. I almost fainted, so I dug in and I was in a room completely in pink wool. There were 6 dubs of iron armor and a few sets of gold armor all p3. I took it to my vault and came back, but I made a realization. I had just raided my old vault. When I quit for a while I guess I deleted my warps, so I forgot about my goodies. I'm such a noob :/
