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.
This page was last updated 05 September 2019
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.
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: 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: 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.
