This is happening on Xbox One. Don’t know about other platforms. I did it ONCE on HEROIC difficult (the first time I entered the Dig), but on my second try (LEGENDARY difficulty) the game crashed to dashboard right before the animation (it didn’t even start). Thus far I’ve attempted to approach it 3 times, but the game either froze or crashed to dashboard on all tries.
So I guess this is game over for now. Please fix it.
