Cannot find legacy packet 201

[uncovery]

My logfile is getting a lot of task exception errors. They stat when someone is logging in only, then sooner or later, they are all what I can see in my logfile. Doing a /irc reload solves this issue temporarily. Running latest version of Spigot. They are all based on the "Cannot find legacy packet 201" issue. Sample error:
