I am in the process of rebuilding two multisite networks. While taking a checkpoint to compare tables in the database I discovered 3 tables are missing from one the the databases: _blog_activity, _comment_activity, and _post_activity. Both networks have the exact same plugins installed and activated. Do you know which plugins created these 3 tables. I have been tracking the tables that are created for each plugin but just in the one database, which is the one with the 3 fewer tables so I don't know which plugins created these tables.
