It’s unclear what you’re trying to report. Is it…
- That you think you’re fulfilling the criteria for Mastery but you’re not getting Mastery granted?
- That you’ve obtained Mastery but it’s not showing in the Conquest window?
If it’s the first one, you need to upload a screenshot of the completion screen.
If it’s the second one, I’d refer you to the stickied thread at the top of the forum…
