Rarity also does not count any sort of attempt. I assume it is related to this error.

What version are you running?` This doesn't seem like the most current release to me.

Also, try enabling ONLY Rarity to see whether this is actually caused by the addon. If you have any other addons messing with the MountJournal API, I'd suspect they might be to blame for the error.

Closing this as resolved since the 8.0.1 release is now publicly available.
