The Silent Cave - Stuck after killing imprisoned boss, no atlas book and can't teleport out..

So... Spent a bit mapping to The Silent Cave, so I can get 2 more atlas points. I lost half a level by the time I made it to him and fighting him. I finally killed him and then he doesn't drop the atlas book! And on top of that, I can't teleport out! I'm literally stuck in the cave. SMH Hope this qualifies as a bug :) Maybe I can get the atlas book at the very least...

The 3 objects in the corner are shown on the mini map, but I can't interact with them. Not sure if you're supposed to. Again, boss is dead.

I switched to my pc and now I'm able to TP out...
