Originally Vivienne's feather will be glued on Geralt's head if you equip it. *Poof* Now it wont :))
Requires Blood and Wine (duh)
Use Script Merger if conflicts happen.

Note: If you already have it equipped and dont know how to take it off, you can do it using in-game console
1.press the ` key to open or close console
2.to remove the feather: removeitem('sq701_item_wearable_feather')
3.to reaquire it: additem('sq701_item_wearable_feather')
