Attributes not stacking.

Put the summary of the bug you're having here

What I expected to happen was...:
Placing gear with attributes in the proper slots should make the attributes stack.

What actually happened was...:
When using multiple items for the same attribute, only the most recent item takes effect.

Steps to Reproduce:
1. Spawn in multiple items that effect an attribute (make sure they use different slots)
2. Try equipping all the items.
3. You should notice that only the last item you equipped takes effect for the attribute.

Note: In the images, notice that my armor bar only reflects the most recent piece equipped. I did the testing, it's not visual. My damage received reflects what is on my armor bar, same situation with the damage attribute on the gear. Strangely, this issue isn't present in items spawned in previous versions.
