Abyssal Depths bug

If the "Abyssal Depths" appears when you click it to fall through and then immediately do a dodgeroll, you'll remain above, on the map, and there are no mobs.

If you go back and fall into it, and then exit, mobs will appear.
But not all. I reached the boss that way, and he wasn't there. After completing the depths, the mobs didn't appear, but the boss did.
