2.7.1 PC version. Nature's Madness should NOT activate Weakness Policy but it does on PO. Information (include relevant logs, replays, screenshots): (If applicable) Sources to confirm the presence of a bug (ex. Smogon): In-game it doesn't activate because it's not a super-effective move. See 8AVG-WWWW-WWW7-45R8 of a battle video of Weakness Policy Hariyama not having it activate when Nature's Madness'd.
