Breaking an Armor Stand Caused the Stand and Armor on the Stand to Disappear

During what appeared to be a lag spike, I attempted to break my armor stand to upgrade a couple pieces of armor from it. I should've shown more concern at the fact it didn't shake when I punched it. As soon as it broke, however, it disappeared along with everything on the armor stand. I looked all around to try to see if they ended up somewhere else in my build, but they were neither outside or inside the building. Considering what I had on that stand... I was pretty heartbroken by this event.

As a side note, while I was playing on the Nintendo Switch version of the game, the server itself was being run by someone playing on the Play Station 4 version of the game, if that helps in any way.
