Hermann Ending Epilogue CG (Shaded)

Hey I don't know where to put that but I'm on the last build of Aura on mobile and I just got a big bug during the quest where you have to kill the demon in the east forest for the white priestess : as soon as i kill the core in his domain i get an error "TypeError : cannot read properties of null" and a bunch of assets listed under, i got a screenshot if you need it
