Falcon wings just gone

Playing D3 many years. With no falcon wings.
Opening all chests i’ve found… and today i just accidently found that mysterious chest and open it…
Wings just gone because of ‘HUSK’ buff (Altars of Rites).

How the hell? Is it normal thing? The only wings that can be found in chest are just disapear. I believe it’s ubnormal behavier.
