First off, I'm playing on Xbox One X and fully updated.
The first bug is one that I'm pretty sure many already know about and that's the missing mouth animations when characters are talking. I'm getting it more frequently now.
Another bug that has started happening lately is that I receive an error when trying to view photos. I get an error message saying "This feature is currently unavailable because a Ubisoft online service received too many requests in quick succession from your account. Please try again later. Visit support.ubisoft.com for more information. [0x20100302]". All I was doing was hovering over photos to get a preview, and after about 3 or 4 photos I get that message. I usually hide all photos not long after starting my game, so I don't know how long this has been happening.
