So I am playing on a minehut server with some other people and I was exploring the end when suddenly i got kicked while bridging over the void. It kicked me and said "flying is not enabled on the server". I was definitely not flying or anything like that, it was just the server having a issue. After I joined the server again, I was in the void falling down. And then I disconnected before I got killed by the void. So my question is, is there is a way to safe my stuff in my inventory? Like somehow turning on keep inventory before I join the server again or something else that will safe my valuable stuff I have in my inventory? Thank you for any response! Daniel
