Look inside the house in both worlds. There is an object in the spirit world you can read about. :3
Same place I'm at, nearly broke my laptop, pressed every key
I read about the greenling, but i can't seem to figure out how to interact with it... The green item and the blue item do nothing with it, or anything else so far.
If you equip the boat shard after you read about the bug you should get a hint. :)
Just look outside, there is someone who wants a...er... favor of you.
