/restart only works from console, and if any players are on, the server will "gracefully" crash.

[progenitor-amborella]

In 1.20.4 I am able to use the mod, but restarting only works from the console when no players are online. If any player is on it will stop, but then crash. Additionally, issuing /restart from the game doesn't have an effect. It will print in console, but nothing actually happens, which is shown here, followed by a console-issued restart.

Duplicate of #24, thanks for the log, and thanks for checking out Restart Server though

I initially was going to comment this on issue #24, but was not sure given the nature of the crash if it should be separate. Thank you!
