Description
When I run the /world command, it tells me "Error: Hole in floor!"

Before everyone starts yelling at me that this is an unsupported server version, this also happened in 1.15.2 which I'm pretty sure is supported. I have already upgraded my server and I'm unable to run 1.15.2 without corrupting my worlds, and going through a tremendous hassle. I understand if you cant help me, but any help would be appreciated.
Steps to reproduce
Download a bedwars/skywars map (void world), load in with multiverse. run /setworldspawn where you would want the spawn point to be. Now go to a different world. I went to world. When I execute the /world [world name], I get the error. Error: Hole in floor!

Even without a void world, when my server was running 1.15.2, I was unable to set a location I wanted everyone to /world to.

I checked all of the essentials commands here: https://sites.google.com/site/mhnpsminecraft/plugins/essentials-commands due to the one in the wiki being down at the moment (https://essinfo.xeya.me/index.php?page=commands), and was uable to find anything related to setting up /world
Expected behavior
I expected to be teleported to the specified world at the spawn locations (even logout location should be fine)
Screenshots
none

It seems to work as expected, no bugs here. The /world command does not teleport you to the world's spawn. It teleports you to the same location you are currently at, in the other world. If you want to teleport to a specific location, use /tppos instead, or another appropriate command.

MC 1.16.1 is supported on Essentials 2.18.0 and higher -- please update immediately to avoid any issues on your server version.

The Error: Hole in floor! message means that it failed to teleport you because the location was unsafe to teleport to, due to there being no blocks to teleport onto.
