Locking same weapon for weapon set swap bugs out damage

When I lock the weapon in Weapon Set 1 and set a skill to use Weapon Set 2, the skill consistently deals significantly less damage after each loading screen. The issue persists until I either unlock and relock the weapon or change the skill gems, after which the damage returns to normal but only until the next loading screen.

The same thing happens in reverse: if I lock a weapon in Weapon Set 2, any skills tied to Weapon Set 1 suffer from the same reduced damage.

It should not register as unarmed. For example, with mace skills, the skill would not be usable without a mace, but in this case the skill still works but deals noticeably reduced damage and it is not visual bug since I tested it in maps.

Bugged damage (Forge Hammer + Hammer of the gods)


Normal damage for comparison


EDIT:
The bug seems to be related to the Keystone "Giant's Blood".

Weapon Set 1 and 2 share the same locked weapon but Weapon Set 2 has a Mace as off hand weapon. But for some reason it is disabled until I do the above mentioned actions.


EDIT 2:
This bug does not occur if I lock a Two-Handed Mace from Weapon Set 1 and use no off hand in Weapon Set 2, or any Mace/Shield combination in Weapon Set 2 that would not require Giant's Blood.
So the bug is very likely related to Giant's Blood.

I can second this. Having the same bug. I also have Giants Blood allocated and the bug only occurs when using a shield /2 handed weapon in off hand. (I have enough strength for giants blood on both trees without any strength from shield/weapon).

same issue

+1

Having the same issue, hopefully it gets fixed. Very annoying to unequip and requip weapons/gems to fix the issue every single instance
