So I was laddering and I'm pretty sure I lost to a bug. Which is upsetting to say the least. Please excuse me being salty in the chat.

This replay shows it. On turn 25 I attack an Alolan Raichu at full with a +1 252 Volcarona's HP Ground and it lives. I calced before making this play and this is what I saw:
+1 252 SpA Volcarona Hidden Power Ground vs. 252 HP / 252+ SpD Raichu-Alola: 316-374 (189.2 - 223.9%) -- guaranteed OHKO
So even if it was maximum invested bulk it should have OHKO'd. He is not AV, he revealed on turn 22 that he was Z-move Alolan Raichu so there was no way any item, including AV, was giving him any more bulk. There were no terrains, no boosts, no nothing. Beyond that,
yes I double-checked my EVs and IVs. Without changing a thing, here is the copy-paste of the Volcarona I was using that, as you saw, was at +1 during the match.
Volcarona @ Firium Z
Ability: Flame Body
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Quiver Dance
- Fire Blast
- Giga Drain
- Hidden Power [Ground]
And this is all assuming it was max bulk, which it definitely wasn't cause that's a trash set. This is the calc I originally ran
+1 252 SpA Volcarona Fire Blast vs. 0 HP / 4 SpD Raichu-Alola: 616-726 (456.2 - 537.7%) -- guaranteed OHKO
So imagine my dismay when I'm laddering for requirements to vote and not only does this somehow happen, but he also gets the 10% para chance on my volc to win.
