[08:22:29 INFO]: [HeadDrops] Disabling HeadDrops v1.5.6

Steps to Reproduce

I am not exactly sure, it happens randomly after rebooting your server. It doesn't happen all of the time. Once the bug is triggered, a config regeneration is required to fix it.

Working to completely redo this plugin. Hopefully can push that out in the next week.

A hotfix for this issue would be nice

Hello, quick update. It is not the config that is being corrupted but instead headLocations.json.

Before the file corrupts itsself, it throws this error in console:

[13:51:40 ERROR]: Error occurred while disabling HeadDrops v1.5.6 (Is it up to date?)
java.lang.NullPointerException: Cannot invoke "org.bukkit.World.getName()" because the return value of "org.bukkit.Location.getWorld()" is null
