Hello everyone, I recently build a stable for my sheeps and after adding a roof I went to make some lanterns for the inside. When I returned all of the animals were gone. No sign of drifters, Wolves or a bear and no skeletons to be found. What happened and can I get the animals back via a command or smth similar? Thanks

Hello, I recently started a server with my friends and I wanted to ask if there is a way to find the seed of the world. And if that is possible, can I use the seed to find limestone because I traveled over 5k blocks and didnt find any Limestone on the surface. Thanks
