Update Packet Events #42
Description
So I am pretty sure that this error is caused by this plugin not being on a new enough version of packet events.

Basically I figured out that if the show_dialog text component is used in any dialog, when a player joins a server with this plugin installed it will send this error in console. This is because the version of packet events this plugin uses has a old version of adventure compiled in it I think.
But anyway the solution is just to update packet events.
