Me and my friend got into playing a lot of Minecraft recently, and we often leave because we have to do other things, so we leave the game. We have a server without mods, is not in offline mode, and is running 1.14.4.
For some reason, all of our stuff is lost, and we have lost interest in the worlds multiple times. I thought it was just not saving, so we took precautions, and we stood still for a minute so it would save, sometimes it would work.
When it didn't we got pretty mad and I couldn't find a solution and nothing online tells me how to fix it. it hasn't happened before and I've been making servers for me and my friends for 2 years now. If someone could help me with this problem, I would really appreciate that.
