Hi, I think I've found a situtational minor bug.
By using these 3 plugins (yanfly core, yanfly battle core, dual wield), if a character equips a weapon that has tag <Twohanded>,
then uses an item that uses gainHP formula such as b.gainHp(Math.randomInt(50) + 51); b.startDamagePopup();, the heal effect becomes twice.
Using <Mainhand> does not cause this bug.
