Unequip at 1 durability setting faulty/blind spots.

[Gerhazo]

Description of Bug Experienced:
Despite the unequip at 1 durability setting being toggled on, an offhand weapon continued to be used and broke after reaching 0 durability.
It -then- tried to unequip it.
[CHAT WINDOW TEXT] [Sat May 18 13:38:37] The item Seeker has been destroyed.
[CHAT WINDOW TEXT] [Sat May 18 13:38:37] Seeker (0/21)
[CHAT WINDOW TEXT] [Sat May 18 13:38:37] Seeker unequipped due to one durability remaining. You can re-equip Seeker, but this is at your own risk.
[CHAT WINDOW TEXT] [Sat May 18 13:38:37] Lost Item: Seeker

My only two theories are:
Either the check doesn't happen when you equip the weapon, so equipping a 1 durability weapon won't warn you.
Or, perhaps the check doesn't work for the offhand slot.

Steps to reproduce the Bug:
Not an easy case to attempt to reproduce on your own.
(Assumedly? This might be what happened?)

1. Have offhand weapon equipped.
2. The check for some reason fails when the durability goes down.
3. The offhand weapon breaks after further use.

Or, perhaps what happened?

1. Equip offhand weapon at 1 durability, perhaps the check doesn't occur when equipping things.
2. The offhand weapon breaks after further use.

Expected Result:
Item gets unequipped.

Actual Result:
The item remained equipped, was broken.

Additional Information/Notes
Perhaps the setting only checks when an item's durability changes and not on equip. If that's the case, it'd be nice to have the functionality extended to cover the latter case too.
Logs below show it being broken and the unequip message arriving late. Perhaps that's the issue, with the "you can re-equip at your own risk", that it doesn't safeguard you from equipping one at 1 durability? Though that seems to be a silly thing to allow.

Not a bug.
The setting can only save items going from 2 to 1, to 1 to 0.
This is by design to allow people to re-equip items if absolutely necessary.
