Hi! So my friends made a server on minehut and we love it. Its been up for two-ish months and when 1.17 came I lost some of my stuff that was placed in my ender chest. I lost a diamond sword that was made the day before the update. But also 3 wither skulls that I collected the same day. That's all I noticed but I noticed in regards of losing items. After the update when I went in to play once again I noticed that I spawned in a different place then what I left of att. Edit: I now realised that everything that happened the day before the update is just not existing. My books that I encanted are not here and I have my old books. A part of my house is gone and so on.
