Me and my friend was just playing a Skywars game from the plugin Skywars: https://www.spigotmc.org/resources/%E2%99%9B-skywars-x-%E2%99%9B-solo-teams-kits-cages-trails-mystery-box-parties.28120/
Then it all crashed out of nowhere. Server performance wasn't bad or anything leading up to the crash it just happened randomly.
