If you do the update you will have to regenerate your config.yml or add the changes manually (see below)
Added the possibility to disable cooldown in some worlds
Code (Text):
#Between each use of enderpearl, the player will have to wait XX (depending on the configuration) seconds (0 = disable)
cooldown: 30
#Disable the cooldown only in some worlds, add between the [] the worlds you want.
#EXAMPLE: [MyWorld1, worldEvent, exampleworld3]
cooldown_blacklist_world: []
