Oh weird, must be a different version, because Mine just shows the dimension numbers, not the names.When server is shut down it write log like this
[21:58:54] [Server thread/INFO]: Saving chunks for level 'world'/Overworld
[21:58:55] [Server thread/INFO]: Saving chunks for level 'world'/Nether
[21:58:55] [Server thread/INFO]: Saving chunks for level 'world'/The End
[21:58:55] [Server thread/INFO]: Saving chunks for level 'world'/Soul Network Dimension
[21:58:55] [Server thread/INFO]: Saving chunks for level 'world'/Spirit World
[21:58:55] [Server thread/INFO]: Saving chunks for level 'world'/Torment
[21:58:55] [Server thread/INFO]: Saving chunks for level 'world'/Mirror
[21:58:55] [Server thread/INFO]: Saving chunks for level 'world'/The Outer Lands
