2 Necropolis Halls Chests issue

Stuck here as well. !9 chests completed on the map but it says 16/17 and 94% discovered. Every quest is done and my next step is the point of no return, so trying to finish the zones. 

sorry, but it's been over a week and I'd like at least an acknowledgement of you getting the file please

I'm on PS5 and I have the exactly same issue. I have all the chests open but it says I've only opened 15/17, so now my map progress is stuck at 88%.

I thought there was an error as well and felt validated when I found this post but after reading the last comment, I dug deeper. I had 15/17 and 88% and counted 18 total chests on my map (includes the fancy one) so was annoyed. But I finally found a YouTube video that walked through where exactly all chests are. There’s is one going up the stairs behind the eluvian and one through a hidden doorway up the rocky ledge to the left before you go down to leave the vault of the beloved to head into the memorial gardens. Check out @MrCodeslinger on YouTube. His Neceopolis video on chests showed me where I was missing them and even walked through how to get them to show if they weren’t initially. 

but EA does need to update the chest count as that is really the issue. 

Confirming that 88% and 15/17 with 18 chests open on the map does still have 2 chests to be found. I was in this situation and used the video to find one mist doorway in the Vault of the Beloved (pretty sure it wasn't there before, and it's gone now) and the Lost Watcher's Wing. I'd just completed Deadly Playtime when I returned to the Necropolis, and I believe that the Lost Watcher's Wing was closed when I arrived. It opened up while I was teleporting around the Necropolis, but the chest was initially non-interactable. I had to travel outside the Necropolis and come back, and then I was able to open the last chest. After completing those two chests, I have 20 chests showing up on the map as open and 100% map completion.

Yes! I have opened 19 total chests and still show only 16 of 17 open. I have no idea where the one I haven't opened could possibly be. I am playing on an Xbox series x so this is a problem across the board with the game. Next update maybe?

I have no idea how to share my saved game, but I’m having the same issue. I’ve clearly explored the whole map and there are 18 opened chests marked on it, but it says I’ve discovered the timelost hoard chest and 15/17 of the other chests. So I’m stuck at 88% complete and it’s driving me crazy.
