I've tried other locations, but I'm pretty sure it has to be a valid location on the map somewhere... not 100% sure though.
You could use
map specific configs to set the location based on maps if needed.
It looks like there are no issues and no other requests for added features... I'll update this plugin on the first post this weekend.
If I find time between now and then, I'll work on an offline command to ban steamIDs even if the player isn't online, then once the player comes online it will execute and save the ban.
