• Possible conflict with JSON packages
• Upgrade /n reload, but please use it carefully and prefer restart/reload.

About the issue which concern BannerBoard :
The problem seems to be a conflict with ProtocolLib. Even if I tried to fix it, the problem doesn't come from Negativity specifically.
I report the problem to the BannerBoard author, and I'm currently talking with him to see how to fix the issue.
