As you can see here at this angle the ground disappears and you need to get closer. It´s only visual but a bug nontheless.
Also when i was trying to do an offering for a whisper to make it into a bigger one i got stuck, no buttons worked and i had to close the game through task manager to fix it.
The one i was stuck on was the last whisper at the Nameless path. A friend had the same bug at another one but he cannot remember which. Same Realm coop btw as well.
