#1 Error while trying to utilize asteroid respawning

[Fingersniffer]

When attempting to use the asteroid respawning command it gave an error and resulted in a file that crashed the server on startup. I had previously ran the command to backup the asteroids and the files were in their default location.

Bat file contents:
@echo off
rem Respawn Asteroid script
echo.
echo SEMU Asteroid Saver.
echo.
echo Drag 'n drop the Space Engineers save folder here and press ENTER:
set /p savedir=
echo.
rem Note how there's no quotation around the savedir. If it's been dragged and dropped, it should have them if needed
set command=semu.exe %savedir% --stop-movement --cleanup-items --respawn-asteroids
echo For those interested, you are about to run the command:
echo --------------------
echo %command%
echo --------------------
pause
%command%
pause

Console Output:
SEMU Asteroid Saver.

Drag 'n drop the Space Engineers save folder here and press ENTER:
"F:\Saves\X,Y,Z - PVP - Custom Mods - No Griefing"

For those interested, you are about to run the command:

semu.exe "F:\Saves\X,Y,Z - PVP - Custom Mods - No Griefing" --stop-movement --cl
eanup-items --respawn-asteroids
