Same here but it only happens on the one handed swords for me on PS5
@bojan-77 Will try this later. I'll keep you updated
@r10rdan As of now this work around has helped me!! Thanks for the info!
@kyokushin_oyama After playing the game and collecting the new weapons (siege of Paris) I can't put runes on any weapons. Let's hope this wil be addressed in the next title update!!
