WowAce

 I've just downloaded the addon, and I'm having an issue with most of my previous attempts on mounts not being tracked. I've tried to re-verify my attempts with the chat command, however, I keep getting an error that says Rarity: Verification failed with 50 errors. This error also says Warning: Found setting for equalOdds but group size is not set. I'm not sure what is causing this error, but I'd like to be able to track all my previous attempts on mounts.

What do you mean exactly? You downloaded the addon, but never used it before (that is, it never tracked any previous attempts)? And now you wish to see what your attempts in the past were?

If so, this generally isn't possible as the addon can only track attempts when it's installed (and those, for the most part, aren't persistent). The only exception is items that can be tracked via Blizzard's statistics API, such as world and newer raid bosses.

The verification is completely unrelated and it verifies the database format instead. Since lots of items aren't using the proper format it will complain, but those are only warnings and not actual errors and not something that would impact the addon's functionality otherwise.

This is more of a developer/debugging feature and you can pretty much ignore it if you haven't added any items yourself. That equalOdds note in particular is left over from when the game swapped to Personal Loot, it only affects the percentage calculation for the likelihood of obtaining any one item. They will eventually be fixed, I just haven't had the time and it's not particularly important because it's purely cosmetical.

I had wondered if it was possible to track previous attempts on older raid bosses and dungeons, because it was already tracking my attempts on newer content. It's not a big deal that this isn't possible to me, but I had thought it was a bug at first due to the verification failure message I saw in chat. I'm continuing to use the addon. Great work!
