Hello I was wondering why my server was putting out this error because I started up the server before hand fine and then when I tried to put sponge on the server it decided just not to work.
The state engine was in incorrect state SERVER_STARTING and forced into state SERVER_STOPPED. Errors may have been discarded
Can you supply a full log? Preferably as a pastebin or similar methods?
There seems to be several things wrong with several mods. The end bit you mentioned isn’t the problem itself just when the server crashed. Might want to look through that and check with those mods/plugins
