We’ve temporarily disabled the consumables that add Guild Improvements and Guild Tactics to the guild storage while we fix an issue related to their use. Guild improvements and tactics already in guild storage are unaffected. The scribe recipes to craft Guild Improvements and Guild Tactics also are unaffected. We are working to get the problem resolved as soon as possible.
