1 more NBT Error was pointed out to me, and I was able to find a quick fix for this issue.

Crystals are not going to be implemented on this update, but they are very close to being done, so I will reiterate this.

Crystals are going to be implemented on the next update, and you can already edit the configuration file for crystals, so you won't need to update the config when they are released.

I will be creating a discord server for support and plugin suggestions/bugs in the near future, so stay tuned for that, most likely will release the discord when I release crystals for this plugin.
