If you have dowloaded the lich skin for the huntress, you may had a problem with the dog's skin wich were glitched. This dowlnload is a fixed version of this dog, but before you choose the huntress/lich, it will look like the regular dog, apart from that there is no bug or glitch.

To intall it, you just have to place the file "CompanionOrbitalCollection" with the file "Guide" that you have installed for the lich skin (in the file "sprites")
