Have the battle stats for the Blood Bat been reset? (or possible glitch?) and if so does anyone know why?

I had all my pets on 10 wins min but now I only have 5 of 80 having battled it at all.

i was curious so i took a look at my own stats for blood bat, which have not been reset. it is possible you got all your wins in before the last reset and just forgot, whenever that was, as when i was farming the mini jellies earlier this week i noticed i had 5 wins counted for the achievement but uncounted for the battle statistics. so my statistics page shows me having 2495 total wins across my pets but the achievement has counted 2500.

absolutely no idea when the last reset was tho. that was before i got more seriously into battling :/a
