Re: Dragon Age: The Veilguard Unique Chests bugged out and unable to be opened.

nope not just those ones people have reported not being able to open the chest after defeating the formless one boss and also the ones in treviso for me cant be opened

Maybe for you, but for me, it's chests that appear on the Map. The larger unique ones that failed for me were the Demon/Dragon at the Necropolis, 3rd Revenant, and basically anything afterwards. I restarted a much earlier playthrough, but it seems bugged still. Someone noted this since the patch. I didn't pay enough attention to confirm or deny, but it would track.
