I'm playing calamity (wotg) and after i beat queen bee i safe&quitted after i went back in the world my caracter was safed successfully (inventory was normal, still had the loot from queen bee) but my world "lost proggress" blocks i broke/placed were back to how it was when generated and the mastermode golden trophy like things you can place where also gone resulting the world not saving that i beat the boss(i know this because queen bee wasn't ticked in bosschecklist) and having to do all over again
the shutting down when afk is self-explanatory
