I got into my previous server in sea of thieves

I was playing by myself on one sloop, and finished my quest and left the game to go get food. when I came back, I joined a new ship on a different sloop (I own two sloops). I scuttled and changed server right off the bat due to the reapers on the map. when I got to the new server, I checked the map board to find my maps from my previous session a half hour ago!
I did sail away from the outpost because I wanted to do my quest but when I told my friend about it he said I should record it and post it so here I am. pretty cool little thing that I don't think I've seen before.
