Hi,
 
 Just posting another update which was requested. Now there is a custom delay you can add to both kinds of join books. This defaults to 2s and is also the minimum requirement.
 
 Make sure you delete your 
config.yml file so the new one may generate.
 
 For on-join-book,
 Just set the delay in the 
on_join_book_delay.
 
 For on-first-join-book,
 Just set the delay in the 
first_join_book_delay.
 
 I hope you enjoy the update and please report any bugs you may face on spigot or on discord! (PS: Review section is not for bug reports!)
