Why did Durin lose his skin in act VIII? I'm so sure he had it in act VII! I've tried finding YouTube videos to get a screenshot as evidence but unfortunately in every video I've checked he is skinless the entire tome, making me think those players either didn't unlock or equip his skin.

I am 100% sure he had it in act vii. I was talking to my partner while we were both doing the archon quest, but he had started earlier than me so he was quite a bit ahead. He mentioned durin not having his skin and I asked what he was talking about, because on my end he had it. I should've taken a screenshot man. Then I get to act VIII and boom - his skin is gone

I'm thinking this has to be intentional, right? On the other hand, what the hell is the purpose of it?
Why did this happen?
