I unlocked Mirri yesterday, she had her items earlier on today, but now she's buck naked, all items gone, weapon armour, everything.
I have never unslotted any of her items. How can this be possible? Yes, I've sold items at the merchant, but is it possible to sell items that a companion is currently wearing?!
If I managed to sell or lose something that was equipped, then this looks like a pretty major bug. Thankfully it was white gear, but I still don't know how I'm going to replace it.
