I am seeing the same issue I have seen in the past with some challengers. When I go to my pets' statistic pages, it's showing battle statistics for unstable snow fairy and chase. I don't have chase unlocked as a challenger but somehow have statistics for him. I am not sure if this is somehow related to the recent lag issues as these are also both battle quest challengers.

I think they came from the battle quests. They acknowledged that the battle statistics page for each individual pet is not keeping track of battles correctly.

Yeah I remember I had a similar problem before and the opponents got removed. Now that it has happened again I see that it's been with battle quest challengers

I have no idea why they are keeping track of withdrawal as losses, considering they don't get recorded for individual challengers.

But then, there's more than that. For example, how did this happen? I'm assuming the individual pet's stats are correct, which I haven't noticed anything weird.

Cinthilocks Name: Fuzie Wins: 10 Ties: 0 Losses: 0 Total 10

Fuzie Name: Cinthilocks Wins: 22 Ties: 0 Losses: 5 Total 27

That was when you searched by challenger and by pet? That is weird. When I search under the opponents I shouldn't have no battles will come up so at least that part looks right for me.

Yes, that's correct. The High Scores also shows the incorrect wins.

I think either the system's using the the wrong way to tally up the battle statistics, or the battles are recorded incorrectly or are in different places. Possibly all of the above, and likely the latter.
