Disarm/Grapple/Shove/Trip - Not using best weapon for item bonus

[7H3LaughingMan]

It looks like the item bonus you get from having an equipped weapon with the relevant trait isn't coming from the best one, but instead the one last in the list. For example if you give someone a +2 Flail and then a +1 Flail and they both have them equipped it's only giving a +1 item bonus and not a +2 item bonus. As soon as you unequip the +1 Flail it decides to give a +1 item bonus, or if you do it in reverse order where you give them the +1 Flail first and then a +2 Flail.
