Bug: Rune Sockets with limit on different Weapon slots

To reproduce this bug:

Slot the same rune with a limit(e.q. Farrul's Rune of the Hunt) on 2 different weapons.

Try to Equip one weapon on weapon set 1 and the other on 2. In my case Talisman on 2 and Hammer on 1.

--> One of them will be disabled.

I dont think thats intended because if you only lock only one weapon for both slots you can use that on both weapon slots and therefore use the same runes on both weapon slots.
