In this update, we've completely recoded the scoreboard system to go from line1: ... to a list of lines.
All your scoreboard configuration lines will be reset to default. You will not lose your current setup, but you will have to transfer the lines.

Recoded the scoreboard system! Added 1.16.2 support.
Added new placeholders to the scoreboards: {players_needed}, {waitingtimer}, {nextevent_time}, {nextevent_name}, {kills}.
Added support for (MVdW)PlaceholderAPI on Scoreboards!
Added support for SlimeWorldManager world storage, enable it in the config.
Fixed scoreboard gap lines for {winnerX} placeholders when there were fewer winners than placeholders; those empty lines will now be removed.
Fixed the {aliveplayers} placeholder on the scoreboard which wasn't updating. It now works!
Fixed the 'clearInventoryOnLobbyJoin' option which was clearing the inventory after giving the lobby items, it now clears it before.
Removed some junk code.
