Unfortunately, not all plugins and mods are 100% compatible with Nucleus. This page lists some of the known issues, and what you can do to work around the issues.
If you know of another incompatibility, please visit us on Discord and talk to us about it.

Reason: UltimateChat does not use the Sponge Chat event correctly and ignores the message channel set on the event. As a result, UltimateChat will send messages out to players on the ignore list, rendering Nucleus' ignore command useless for chat.
Resolution: None known.
Reason: Simple Tags overrides the "header" section of the chat message on a late priority and will remove anything there, including Nucleus tags.
Resolution: Remove SimpleTags (it is no longer under development anyway).
Reason: The Nucleus Core Mod uses the same mod ID as the Nucleus Sponge plugin. Forge will throw a Duplicate Mod ID error when trying to load this plugin with the Nucleus core mod.
Resolution: Do not use the Nucleus Core Mod. We will not change the Nucleus mod ID - it may break plugin compatibility and, honestly, we were first with it!
Reason: UltimateChat does not use the Nucleus chat formatting by default, but this can be used by adjusting your UltimateChat settings.
Resolution: Update your UltimateChat configuration to use Nucleus chat formatting.
Reason: UltimateCore is another essentials style plugin and may conflict with Nucleus.
Resolution: Remove either UltimateCore, or be extra careful and ensure that modules do not conflict.
Reason: By default, ProjectWorlds will override Nucleus' first spawn mechanics.
Resolution: Update to a ProjectWorlds build after 2nd September 2019, and set "options.first_join.enable" to "false".
Reason: ProjectWorlds has world access permissions that can block cross world teleports.
Resolution: Grant users the ProjectWorlds world access permission, which is "pjw.worlds.<worldname>".
Reason: FTB Utilities alters the chat and may override the Nucleus configuration.
Resolution: Disable FTB Utilities chat-override options, specifically the option "B:override_chat".
Reason: PokeTeams prevents the normal chat event from reaching Nucleus when chatting in teams or alliances.
Resolution: Do not allow team/alliance chat if you always want chat tags.
Reason: Topography has the ability to take control of cross-world teleports in non-standard configurations. SkyFactory 4 has some worlds with this option enabled by default, which blocks the Nucleus teleport commands
Resolution: Check topography configuration files for any "captureTeleports" options and remove them.
Reason: ProjectPortals may override some teleport related commands such as `/back`, `/warp` and `/home` if some of the ProjectPortals modules are enabled.
Resolution: Disable the module affecting the commands in PJP or prefix the command with "n", that is, "/back" -> "/nback".
Reason: ProjectWorlds is a world management plugin and takes over the /world command.
Resolution: Use /nworld for Nucleus management commands.
