A worldspace master record is being injected into another plugin.
This can happen if a patch expects a different version of a master plugin. Typically the patch was made for a newer version of the master plugin adding the injected worldspace itself. The master plugin is the one the worldspace is injected to. Install the correct versions of the involved plugins.
This is most likely not intended and an error. The unneeded worldspace and its data should probably be removed from the plugin among other updates that might be required for converting the plugin for the different game.
