Spigot Build: #735 ChairsReloaded Build: v1.22.0 Crash Report: http://pastebin.com/gWrD5Mji I had an issue with this type of crash not too long ago, and after removing and testing plugins, I finally noticed the crash stopped after removing our ChairsReloaded plugin. So now down the road, they had many updates to their plugin, so I gave it another try, and low and behold, and hour of up time and the server crashed. So when I went to the ChairsReloaded bukkit dev page (Here) I noticed in the comments below, others have had the exact same crash using spigot+chairsreloaded. The plugin developer claims it works great with normal craftbukkit, so I thought I would report the issue here, maybe it can be resolved. Thanks!
