v2.13.2 - Fix knockback when blocking hits in 1.9+
You should update the config to run this version (changes below, the new option is enabled by default also if it is not present in the config).
Changelog:
Added the option to disable the normal/sprinting/in-air knockback module to let the Spigot server handle it. This was requested by a user who wanted to use a custom Spigot for knockback and KnockbackMaster for the combo mode.
Fixed a bug in 1.9+ where players that were 100% blocking hits with shield still received the related knockback.
Please report any potential bugs with this new version.
