I played a Minecraft world on hardcore a couple of weeks ago and now I've already achieved a lot in the world and would therefore find it a shame if I lost the world now. So is there a way to change the world from a hardcore world to a normal survival world?
You can enter / gamemode survival
That just changes the game mode of the player, not the world…
Are cheats activated? If not do that in the settings of the world and then enter / gamemode 0
