The Starhorse Mask has a bug where if you equip another skin with the mask (such as the Master Rahool mask or the Colonel mask), you will not be able to re-equip the Starhorse Mask skin. Additionally, when I went to re-acquire the mask from my collections, I was unable to do so. (However, I could re-acquire the Master Rahool and Colonel mask). I really loved this mask and I would be sad to see it go. If anyone could help me find a way to get it back, that would be really appreciated!
