So, i tested it out again, it came back as true.
Something else i should note is that during gameplay (where two-handed weapon removes offhand item, making it empty), it does behave as intended, HOWEVER, i am reminded of something, there was an instance where I've had the plugin act funny:
When i had first encountered the issue of the two-handed weapons attacking twice, i tried out my own solutions at first, that being i turned every character into a "Normal Slot-Type" character until they equipped a "Dual Wield" Weapon, where in which they'd become "Dual Wield Slot-Types" from a trait inside the respective weapon.
So i had it set it so "dual wielding" would be activated by equipping one weapon (basically I set it so the slot-type would change upon equipping said weapon) yet for whatever reason, when i had done so, the game did something really weird during combat, where my character was attacking with dual wielded seperate attacks (as intended), but after the first attack, it immediately auto corrected to a "Normal"-Slot Type character (MID-Battle, not like... after battle but MID BATTLE), any weapon with the dual wield slot type trait did not switch my character back to dual wielding, just kept it in "Weapon; Attachment" rather than going to "Weapon; Weapon".
Additionally, when this oddity occurred, it did the "double" attack. One normal, one blank.
