This is the summary of the bug I am having.
When you load bow1 (damage: 89 of 100 for example) and when you click then on bow2 (damage : 10 of 100) in the hotbar, the damage of bow2 will be equal to the damage of bow1 (bow2 has now a damage of 89/100).

What I expected to happen was...:
Describe what you thought should happen
I thought that nothing should happen to the damage of the bows

What actually happened was...:
Describe what happened
The damage of one bow is changed

Steps to Reproduce:
1. Place bow1 and bow2 in the hotbar
2. Load bow1
3. Click, while bow1 is still loaded, on the icon of bow2 in the hotbar
4. Now will the damage of bow2 be the same as the damage of bow1 (if the damage of bow1 is 67, the damage of bow2 is also 67)
