@DiamondArrow Absolutely, I'll look into the possibility of supporting nucleus for chat formatting.
@Khaoz It's looking like your database cannot be reached when the plugin needs to.
Is your sql server local or external? Do you get this error after the server has been running for some time? What are your database's settings for the connection pool (max connections / idle time / max life time etc).
I prefer issues to be reported here so that other people can easily find it in the future.
