You have two iron daggers that stack in your inventory. You favorite them and then assing the number 1 to them in the favorites menu. You press 1 and your char equips an iron dagger. You press 1 again and your char equips a second iron dagger. Works great.
Scenario 2: using two daggers of the same type but different quality (works as intended)
You now find an iron ingot and improve one of the daggers to a fine iron dagger. The two daggers no longer stack and the fav hotkey now only works on one of them. You need to favourite both items and use two numbers as hotkeys. Expected behaviour.
Scenario 3: using two daggers of the same type and same improved quality (broken)
You find another iron ingot and improve the other dagger. Now you have two iron daggers of the fine quality that stack in your inventory. You favourite them and the stack ends up in the favourites menu. You assign the number 1 as the hotkey. Press 1 and your char equips one iron dagger (fine). Press 1 again and you now unequip the dagger instead of equiping a second. Not only that but the second press clears the hotkey so pressing 1 for the third time no longer has any effect and needs to be set again in the fav menu.
This should be easy to fix, since improved items of the same quality already have the same behaviour as items of basic quality in the inventory, it only needs to work the same in the favorites menu as well. I'm sure the devs can fix this on a coffee break

Thanks for the patches released so far.
