Just for context, in case is necessary: LottusLifesteal is a core custom made plugin for the server to add some new mechanics and create bridges between plugins that have no built-in compatibility. The only chat-related feature from this plugin is to send the messages from AdvancedChat to BetterChatBubbles, so messages from the public channel display as a chat bubble on top of the player's head.
